     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As required, a detailed illustrative embodiment of the present invention is disclosed herein. However, techniques, systems, and operating structures in accordance with the present invention may be embodied in a wide variety of forms and modes, some of which may be quite different from those in the disclosed embodiment. Consequently, the specific structural and functional details disclosed herein are merely representative, yet in that regard, they are deemed to afford the best embodiment for the purposes of disclosure and to provide a basis for the claims herein, which define the scope of the present invention. The following presents a detailed description of a preferred embodiment (as well as some alternative embodiments) of the present invention. 
     The present invention contemplates a system for associating requests with potential respondents to those requests and comprises: (i) a user originating a request; (ii) associating at least one category designation with said request, the category designation selected from a predetermined list of category designations; and (iii) providing at least one potential respondent with access to said request based on said at least one category designation, each potential respondent having selected said at least one category designation for association with itself. 
     Preferably, the system user selects the category designation(s) for association with the request. As used herein, the term “system” may include a method, a software system, a software method, a computer-automated system, a computer-automated method, etc. As also used herein, the term “request” is intended to include a communication that explicitly or implicitly asks for or solicits something to be given or done in response to the request and includes, but is not limited to, requests to purchase, requests for proposal, requests for quotations, and requests for information. 
     In a preferred embodiment, the system of the present invention contemplates associating requests for the purchase of goods or services or both with potential suppliers of those goods or services or both and comprises: (i) a system user originating a request for purchase of goods or services or both; (ii) associating at least one category designation with said request selected by the user from a predetermined list of category designations; and (iii) providing at least one potential supplier of said goods or services or both with access to said request based on said at least one category designation, each potential supplier having self-selected said at least one category designation for association with itself. 
     The system of the present invention provides individuals and entities initiating requests, such as communications including requests, with enhanced capability for communicating those requests to potential respondents to those requests that have expressed an interest in some characteristic of the request, such as a category designation, thereby improving the likelihood of a response to the request. For example, the system provides buyers of goods and services with the opportunity to easily distribute their specific purchase requirements in their own defined content and format to suppliers, such as suppliers of those goods and services. In addition, the purpose of the system of the present invention is to provide suppliers of goods and services with targeted, active, and current information from buyers of those goods and services that are ready to buy those goods and services. Suppliers are themselves qualified with respect to the category designation subject matter because they have each self-selected that category designation as being of interest to themselves. 
     In a preferred embodiment of the system of the present invention, a potential buyer who is prepared to make a purchase of goods or services (or both) or is contemplating such a purchase creates a request for purchase in electronic form by posting to the system a communication that includes: (i) a user-defined request for purchase content; (ii) at least one category designation selected from a pre-determined list of category designations that classify goods and services. This list of category designations may be pre-defined. In an alternative embodiment, the category designation or designations to be associated with the request may also be suggested or selected by the system via an analysis of the content of the request. The system may parse the request for the presence of predefined keywords. For example, if the keyword “computer” is contained within the request, the system may associate the “electronics” category with the request automatically. The request for purchase may also optionally include the date or time at which the user desires the request to expire. The potential buyer user creates at least the content of the request for purchase information and, preferably, the format of that information. The communication is then posted to the system. The system includes at least one community of suppliers, such as vendors, that have subscribed to the system and have associated themselves with at least one category designation. Preferably, this at least one category designation is a designation that the potential buyer has also selected. The system associates the buyer&#39;s request with the community or communities associated with the category designation(s) selected by the buyer and posts the request (i.e. communication) to a venue that is accessible only by those suppliers that have associated themselves with the at least one category designation that the buyer has associated with his or her request (or the system has suggested or selected on behalf of the potential buyer). Authorized system administrators may have access to all venues without such restriction. (For the sake of clarity, a venue may also be referred to as a traderoom.) In the case where no suppliers have associated themselves with the at least one category designation that the buyer has selected, the communication can still be associated with a venue having a relevant category designation. A supplier subsequently subscribing to the venue would have access to the request if it were still active. This venue provides a repository for all communications from buyers that have associated the category designation with their communications, thereby limiting the communications available to suppliers to those communications having a category designation associated with them that the suppliers have selected as being relevant to their vending of goods and services. 
     Since the communication is posted only to a venue or venues with which the category designation or category designations in the communication are associated, the communication is accessible only to suppliers that have selected those category designations describing those goods or services. In a preferred embodiment, communication with the present system may occur over a network, such as the Internet, LAN, WAN, peer-to-peer, client-server, wireless, Ethernet, local telephone exchange, interexchange, telecommunications, cable television, broadcast, switched, dedicated, Voice over IP (VoIP), Wi-Fi, or WiMAX network, or a hybrid type of the foregoing networks (or any network similar to the aforementioned networks). Preferably, the system may also be implemented as a user-friendly website to facilitate access by suppliers and potential buyers. Communication between suppliers and potential buyers, including requests and replies, may comprise any electronic communication or message facility, including, for example, direct emails, electronic bulletin board postings, newsgroups messages, electronic forum conversations, or any other form of electronic media or conversation. These communications may be stored in an actively managed, operational, analytic, relational, object-oriented, hierarchical, or hybrid types of databases or other storage mechanisms along with user profiles (including usernames, contact information, passwords, and any other user-supplied or derived information) of users (i.e. potential buyers and suppliers) of the system. 
     Further, additional classification features can be included that permit additional criteria to be used in associating communications with groups of suppliers. For example, buyers who are required to purchase items or volumes of items from favored categories of suppliers may be provided with additional codes that permit the association of a code with a communication so that the communication is available only to suppliers that have identified themselves with that code. 
     The system also provides a mechanism for members of a closed user group to publish to or communicate with one another while permitting publishing to or communication with other parties outside the closed user group (and vice versa) based upon a combination codes which identify the group and subscription level of the user. 
     Content, such as requests, posted by originator-users (such as buyers) is effectively pushed to potential respondents (such as suppliers) who have self-associated themselves with the corresponding content by selecting appropriate category designations. This may be accomplished through the potential respondent subscribing to a venue that is defined by a relevant category designation. A supplier, accessing a venue associated with a category designation that the supplier has subscribed to, is provided only with requests for purchase that have that category designation associated with the requests; therefore, the supplier has access only to requests for purchase from buyers that are: (i) targeted to that category designation; (ii) are actively interested in purchasing goods or services associated with that category designation; and (iii) are currently interested in purchasing as of the date of the creation of the communication. In addition, each communication is available to new supplier users who subscribe to that category designation after the posting. Suppliers that are subscribers at or after the time of posting have access to posted communications. The venue acts as repository for buyer communications so that the initial buyer-to-supplier information flow can be not only real time, but also time-lagged or asynchronous. Each communication is available to new supplier users who subscribe after the posting. The system creates a distinct original “repository” for all original communications, i.e., the “main document” originated by a particular buyer user. By threading, all subsequent communications are based on the original buyer-created communication, thereby eliminating any ambiguity as to the content of the original request for purchase communication. 
     Each supplier subscriber to a venue, having access to a venue and to the communications associated via category designation to that venue, is able to reply privately and directly to the buyer generating the specific communication. These communications between a supplier user and a buyer user are private to the supplier user and buyer user, although they are threaded to include the original communication that initiated the thread. 
     With regard to amending or changing a request, the system may be structured to provide for the specific case of amended originator-generated requests, such as RFPs, requiring the originator (buyer user) to withdraw the original request (i.e. communication/document) and to submit a replacement request, such as a resubmitted amended RFP. 
     Turning now to a preferred embodiment of the present invention, the system centers around a set of message venues, or traderooms. Each venue is defined by the one or more category designations so that requests can be associated with venues that are relevant to the designation(s) and the venue. In effect, the venue&#39;s category designation definition becomes descriptive of the category designation(s) of requests that will be posted and associated with the venue, such as category designations descriptive of goods or services that are to be vended through the intermediation of that venue. These category designations are formed into a list of such category designations. 
     A subscriber to the system, whether originator or potential respondent (for example, buyer or supplier, respectively), identifies a category designation (i.e., a venue) based on the category designations of goods and services that are of interest to the subscriber. The user subscribes for the purpose of initiating or intermediating sales (i.e. buying or vending goods or services) through that venue, thereby causing the system to display all posted communications associated with the category designation(s) defining the venue. (The user may additionally subscribe for the purpose of receiving news or information relating to the category of goods or services defined by the category designation.) To facilitate the subscriber&#39;s selection, a search facility is provided for locating and selecting venue(s) based on a match between system category designations and the words used in the subscriber&#39;s search query. Or the subscriber may enter descriptors of relevant request content, such as descriptors of goods or services. If such a search is conducted, the identity of the venue or venues having categories responsive to the search are displayed, and the subscriber can select from that returned search result in order to subscribe to that venue. In a similar fashion, the subscriber can unsubscribe from a venue and thereby disable the system mechanism that delivers messages associated with that venue&#39;s category. 
     A buyer user posts a new buy request (communication of request for purchase) by entering a summary of the buy request with specific substantive content, selects one or more subscribed venues (using a search facility if desired) and either enters a user-defined buy request of specific content and format or attaches a previously created buy request of specific content and format. The attachment may be in various document formats, such as (.txt, .rtf, .htm, .html extensions); Microsoft WORD™ format (.doc, .mcw extensions); Microsoft EXCEL™ format (.xls, .xlw extensions); Adobe™ portable document format (.pdf extension); Corel WORDPERFECT™ format (.wpd extension); or Lotus 1-2-3™ format (.wk1, .wk3, .wk4 extensions), or any other software or file type extension capable of storing data. The attachment may be transferred or uploaded to the system via any available data transfer network facility, including HTTP upload functionality or File Transfer Protocol (FTP) or other like protocols designed to transfer data. A supplier subscriber merely subscribes to one or more venues by selecting the venues based on the categories of goods or services with which each venue is associated thereby activating the system mechanism which delivers content posted to those subscribed venues to the supplier subscriber. 
     On receipt of a buy request (preferably associated with one or more venues by the self-selection of relevant category designation(s) by the posting buyer), the system posts the communication to each of the venues with which the communication has been associated by category designation. Any supplier subscriber that is subscribed to the associated venue will see the posted communication. Only supplier subscribers to the intermediating venue(s)—and the original poster—are able to see the original poster&#39;s communication, except for authorized administrators. In a preferred embodiment, supplier subscribers are notified whenever a communication or request for purchase is posted to a venue to which the supplier subscriber has subscribed. 
     A reply by a supplier subscriber to a communication of request for purchase (i.e. a sales opportunity) may be made by the supplier subscriber entering a subject as a quick message or by entering a subject and attaching a prepared document and/or entering a reply. Such replies are sent only to the original poster of the sales opportunity. From that point, private, bilateral correspondence can continue between specific supplier subscribers and the original poster. The system organizes sets of such bilateral correspondences as threads originating with the original post. Optionally, a supplier subscriber may provide a supplier profile for themselves as an information guide to buyer users. 
     Turning now to a specific example illustrative of the system of the present invention, and as illustrated in  FIGS. 1 through 7 , wherein like numerals indicate like elements throughout, a system of the present invention implemented as an automated information system provides a user, upon successfully logging into the system, with a navigation menu  1000  (as illustrated in  FIG. 1 ) that permits the user to select a single choice. Specifically, “Help”  100  takes the user to a help facility. “Managing Traderooms” (venues)  200  takes the user to a facility for managing subscription(s) to traderoom(s) (venue(s)). “Sales Opportunities”  300  takes the user to a facility for viewing sales opportunities. “Buy Requests”  400  takes the user to a facility for managing the user&#39;s requests to buy. “Mail &amp; Messages”  500  takes the user to a facility for managing mail and messages. “News &amp; Information”  600  takes the user to a facility for managing news and information. “Manage Accounts”  700  takes the user to a facility for managing the user&#39;s account information. “Logout”  800  logs the user out of the system. 
     Referring to  FIG. 1 , navigation menu  1000  may comprise an electronic table of contents, a graphical menu, a series of hyperlinks, a series of clickable buttons, or any other navigational menu or clickable menu bar used to navigate and interact with the present system. 
     If the user selects “Manage Traderooms”  200  (as illustrated in  FIG. 2 ), the user is taken to a facility where previously selected Traderooms are displayed and the user may elect to manage his or her subscription to Traderooms (venues) in which case the user may:
         (i) select search option  204  to search for Traderooms by first navigating to the search page at navigate stage  216  and entering keywords or phrases to display Traderooms respondent to that search at search text stage  208 . After entering keywords or phrases at search text stage  208 , the user may click the search command button  220  and the page is submitted to the system at submit stage  222 . Matching Traderooms are displayed to the user at results display  228 , and the user selects either to view one or more matching Traderoom&#39;s sales, buy requests, or news and information at select stage  230 . The user&#39;s selection is confirmed at submit stage  232 ;   (ii) select a Traderoom using keywords by clicking on an icon (e.g., a “+” symbol icon) at keywords icon  210 . The system displays a table showing the Traderoom display code and all keywords associated with the Traderoom, and the user has the option to subscribe to this Traderoom and all associated Traderooms;   (iii) elect to subscribe to Traderooms for “Sales Opportunities”, “Buy Requests” or “News” at stage  206 . The user&#39;s selection is submitted to the system at submit stage  218  and the user&#39;s currently subscribed Traderooms are displayed to the user at Traderoom display  202 .       

     Additionally, the user may have several options to facilitate navigation of the “Manage Traderoom” facility. For example, the user may click on an icon (e.g., a “A-Z” icon) at stage  212  to toggle the “Manage Traderoom” facility between ascending and descending alphabetical order at submit stage  224 . Also, the user may click a second icon (e.g., a “Top” or “Bottom” icon) at stage  214  to navigate to the top or bottom of the “Manage Traderoom” facility at stage  226 . Traderooms are organized into hierarchies such that, in an alternate embodiment, subscribing to a higher level Traderoom results in subscribing to its associated lower level Traderooms. 
     If the user selects “Sales Opportunities”  300  (as illustrated in  FIG. 3 ), the user is taken to a facility where the user may elect to interact with Sales Opportunities, and the user may:
         (i) elect, at view stage  302 , to view all Sales Opportunities and the unexpired Sales Opportunities with any previously “deleted” Sales Opportunities being displayed at display  316 ;   (ii) elect to “delete” a selected Sales Opportunity at delete stage  304 , and confirm the deletion at confirmation stage  318 , in which case, the selected Sales Opportunity will be hidden from the view of the current user at display  326 ;   (iii) elect a “Where” facility at stage  306  to see the Traderooms (venues) where the Sales Opportunity is posted and have the option to view the Keywords (category designations) associated with each Traderoom (venue);   (iv) select a detailed view of a Sales Opportunity at document stage  308 , in which case a document reflecting a Sales Opportunity may be displayed as a PDF-format document in a new browser window at PDF window  320 ;   (v) elect a “Reply” facility at reply stage  310  and create a reply message to the specific Sales Opportunity by: (i) entering the subject of the reply message into a text box; (ii) optionally electing to send a “Quick Message” by indicating that the subject contains the entire message; (iii) browsing for a previously prepared file for upload as an attachment to the Reply and/or enter a text message directly into the Reply; and (iv) sending the Reply, in which case the information in the Reply is stored in the system of the present invention. Uploaded attachments in supported formats are converted to PDF format for convenience and uniformity. The Reply is only visible to the subscriber who posted the Reply and the user that posted the original Buy Request;   (vi) elect a “Close” facility at close stage  312  in which the user selects either “sold” or “did not sell” as a result of the Sales Opportunity. If sold, the user can provide the sale price and the name of the customer; if not sold, the user can provide reasons via text entry. If subscribed to the Archiving feature, the user may also elect to receive an archive of the transaction and provide a different e-mail address at which to receive the archive. If Archiving has been subscribed to, the user receives an e-mail containing summary information and the individual posts and messages, preferably as an attachment to the summary; and   (vii) report unsolicited or unrelated Sales Opportunities (i.e. spam) at report stage  314 . The user is asked to confirm the spam report at confirmation stage  322 , and the report is submitted to authorized administrators for review at submit stage  324 .       

     If the user selects “Buy Requests”  400  (as illustrated in  FIG. 4 ), the user is taken to a facility where the user may elect to interact with Buy Requests, in which case the user may perform any of the following:
         (i) elect to view all unexpired Buy Requests at replies stage  410  and see the date a Buy Request was posted and the date it will expire;   (ii) select a “Where” facility as previously described in connection with a Sales Opportunity by clicking on icon  406 ;   (iii) select a “Document Summary” at summary stage  408  and view a PDF-format summary document in a new browser window  416 ; or   (iv) elect to post a new buy request at post stage  402 . If the user elects to post a new buy request, the user may: (i) enter the subject of the buy request into a text box, optionally electing to check on a “Quick Message” option thereby indicating that the subject contains the entire message/buy request; (ii) select Traderooms previously subscribed to for the Buy Request or search for new Traderooms; (iii) browse for a file the user has previously created for upload as an attachment as a part of the Buy Request or may enter a text message directly as a part of the Buy Request or both; (iv) select the amount of time the Buy Request will remain active; and (v) select one or more Supplier Diversity/Sales Opportunity Filtering categories (if subscribed to Supplier Diversity and/or Sales Opportunity Filtering). Finally, the user may post the Buy Request and the information contained within the Buy Request is stored in the system of the present invention. Preferably, the attachment and remainder of the Buy Request are in PDF format for convenience and uniformity.   (v) elect to withdraw a buy request by clicking on icon  404 , in which case the user may: (i) select from among a set of standard reasons for withdrawing the Buy Request; (ii) provide additional reasons for the withdrawal by text entry; and (iii) if subscribed to the Archiving feature, select to receive an archive of the transaction and provide a different e-mail address for delivery of said archive. If Archiving has been subscribed to, the user receives an e-mail containing summary information and the individual posts and messages, preferably as an attachment to the summary. The user confirms the withdrawal at confirmation stage  414 ;   (vi) elect to close the Buy Request at close stage  412  and the user: (i) selects either a “bought” or a “did not buy” as a result of the Buy Request; (ii) has the option to extend the life of the Buy Request; (iii) can select from among a set of standard reasons the user did not buy; (iv) can provide an additional reason by entry of text; (v) can enter the purchase price associated with the Buy Request; (vi) sees a list of all suppliers/vendors responding to the Buy Request; and (vii) if subscribed to the Archiving feature, can elect to receive an archive of the transaction and provide a different e-mail address for delivery of the archive.       

     If the user selects “Mail &amp; Messages”  500  (as illustrated in  FIG. 5 ), the user is taken to a facility where the user may elect to manage its mail with respect to the system in which case the user may:
         (i) delete a message from view by clicking on delete icon  502 . The system may hide the message from view at hide stage  514  until the user elects to view all messages or until the message expires and is removed from the system by the system;   (ii) view a message by clicking on text in the “Subject” column corresponding to the message(s) the user desires to view at view stage  504 . The associated message(s) are displayed to the user at display stage  516 ;   (iii) select a subscriber profile of another user who has sent the user a message by clicking on the text link in the “From/To” column at profile stage  506 . This link displays a facility with a summary of subscriber information, including information such as company name, address, email address, telephone number, web site URL, a subscriber-provided text description of the company, a list of Traderooms and Keywords (category designations) that the subscriber has subscribed to for Sales, such as the subscriber&#39;s products and services, and an option to view the subscriber&#39;s registered certification documents;   (iv) report unsolicited or unrelated messages (i.e. spam) at spam stage  510 . The user confirms the spam report at confirmation stage  518 , and the report is submitted to authorized administrative personnel at submit stage  520 ;   (v) view all messages, i.e. display all messages for the current user including those hidden as described above, by clicking on “View All” button  512 . The “Mail &amp; Messages” facility is redisplayed with all available messages at redisplay stage  522 ;   (vi) select a “Reply” facility at reply stage  508  and create a reply message to a received message by: (i) entering the subject of the reply message into a text box; (ii) optionally electing to send a “Quick Message” by indicating that the subject contains the entire message; (iii) browsing for a previously prepared file for upload as an attachment to the Reply or entering a text message directly into the Reply, or both; and (iv) sending the Reply and the information in the Reply, which is stored in the system of the present invention. Optionally, uploaded attachments are converted to PDF format for convenience and uniformity. The Reply is only visible to the subscriber creating the reply and user that posted the original message.       

     If the user selects “News &amp; Information”  600  (as illustrated in  FIG. 6 ), the user is taken to a facility where the user may elect to manage its news and information with the system in which case the user may:
         (i) elect to post a news article at post stage  602  whereby the user is taken to a facility where the news article can be posted by entering a News Article Title, selecting an already subscribed Traderoom or search for new ones, browsing for any accessible file for upload or entering a text message and/or selecting the amount of time the News Article will remain active in the system;   (ii) delete a News Article by clicking on delete icon  604 . The user confirms the request for deletion at confirmation stage  612 , and the “News &amp; Information” facility is reposted and refreshed at repost stage  614 ;   (iii) select a “Where” facility (as previously described) by clicking “Where” icon  606 ;   (iv) click on the news article Title to view the article at summary stage  608 . The article is opened in a new window as a PDF file in browser window  616 ; or   (v) report unsolicited or unrelated articles (i.e. spam) at spam stage  610 . The user confirms the spam report at confirmation stage  618 , and the report is submitted to authorized administrative personnel at submit stage  620 .       

     If the user selects “Manage Account”  700  (as illustrated in  FIG. 7 ), the user is taken to a facility where the user may elect to manage and maintain its account information with the system in which case the user may:
         (i) elect to order an upgrade of their subscription to the system by clicking order button  702 ;   (ii) view or manage their Registered Business Status at status stage  704  under which the user views a table showing their current posted, Registered Business Status certification documents, can view the document by clicking on its title, has an option to withdraw any document if the user is viewing their own Registered Documents page, sees posted date and expiration date for each document and can post new documents if the user is viewing their own Registered Documents page;   (iii) select the user&#39;s current subscriber profile by clicking on the “Current Subscriber Profile” button  710 ;   (iv) elect to view information explaining Special Diversity and/or Sales Opportunity Filtering Programs by clicking on the “Special Diversity” button  712 ;   (v) elect to participate in the Special Diversity and/or Sales Opportunity Filtering Program at program information stage  714 ; or   (vi) by entering their password at password stage  706 , update account information at update stage  708 , including password memorization, Supplier Diversity Program and/or Sale Opportunity Filtering participation, or receipt of an Archive of transactions. The user clicks on “Update All” button  718  to update their account information in the system database, at which time the user&#39;s password is validated (e.g., passwords may be required to be a minimum length or include both numbers and letters) at validation stage  720 . If validation stage  720  is approved, the update page is submitted at submit stage  722  and the inputted password is matched against the user&#39;s password in the system at verifications stage  726 . If the user&#39;s password is not potentially valid at validation stage  720  (e.g., the password field is empty or too short), the password display  724  is presented to the user. At verifications stage  726 , if the user&#39;s submitted password is correct (i.e. matched with the stored password for the user), the user&#39;s account information is modified in the system database at database commit stage  716 .

     In the system of the present invention, requests and their associated communications and/or documents, are associated with venues. When posting a Buy Request, the Buy Request document by virtue of the venue associations (i.e. category designation) selected by the poster is associated with the venues. Consequently, the category designation(s) control traffic entering a venue. Users of the system, as a class, are not associated with any particular industry, service, good, or product. This is the inherent flexibility of the system of the present invention and the conceptual device by which the system can be used by virtually any user to communicate with any other user over a virtually unlimited range of category designation concepts. Supplier subscribers may select any venues/category designations (except where limited by other system features such as group memberships), indicating interest in those venues and associated goods and services. Although this associates a set of goods and services with the supplier subscriber which may be viewed in the Subscriber Profile, it does not define or limit the supplier subscriber; i.e. subscriber selections for venues relating to Sales Opportunities may not be construed to fully define or limit the user. Venue selections are fluid and flexible and may be changed by users from moment to moment. Transactions may or may not be consummated within the system. The requestor/prospective buyer may remain anonymous on initial posting, but loses anonymity on posting a reply to a supplier reply. 
     From the foregoing description of the preferred embodiments, which embodiments have been set forth in considerable detail for the purpose of making a complete disclosure of the present invention, it can be seen that the present invention comprises a system for associating requests with potential respondents to those requests, such as for use in potential purchasing of goods and/or services, knowledge-based inquiries, and matching common interest groups. It will be appreciated by those skilled in the art that changes could be made to the embodiment described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiment disclosed, but it is intended to cover all modifications that are within the scope and spirit of the invention as defined by the appended claims.
