You may access gophers from a hypertext link at many WEB sites, or you would have to call up the Gopher system. These lists are used by people to share information on a particular subject. Mail Lists and Listservs utilize the e-mail function of the Internet.
People subscribe to an address on a subject of interest.
Whenever anything on that subject is sent to the list site address it is then disbursed to all of the subscribers. Mail lists and Listservs are basically the same but with one difference, the disbursement of mail on a Mail List is done by a person known as an Administrator. The Listserv is a computer program that automatically distributes the mail to its members. You must subscribe to a list and unsubscribe if you no longer wish to participate. One word of caution, make sure you frequently check your e-mail and delete messages from your mailbox you do not want to keep.
