We have the software to upload your site into this space, and to make any changes at any point in time If changes are made they are instantly available to users of the Internet. However it may be some weeks before search engines alter the data in their data bases. This is not normally a problem, provided you site was properly indexed in the first place. For example if you alter you telephone number, then anyone finding your site through a search engine will find the new number, but if you put on a new page about, say, the solar eclipse, then it would take the search engines some weeks for this information to be available to searchers. I cannot stress this too much.
Internet users expect instant replies, tomorrow is too late.
By then someone else will have given them the information and they will have taken their business elsewhere. If your new web site is your only source of e-mails, then you stand the danger of getting bored. There are lots of places on the web that send daily bulletins on any subject under the sun, there are news group with regular updates on anything from genealogy to golf, you can subscribe to the joke of the day. Whatever it is find some way of getting e-mails. I labour this point because once someone e-mails you the chances are that they will buy whatever it is you are selling, but if you do not follow up immediately, then you have lost the opportunity.
