We need a script which will allow us to do the following 3 things: 1) Allow us to enter in keywords, which will then search through a choice of search engines as deep as we select. Then for each returned web site, we need to be able to extract the contact email addresses from one or two pages deep. 2) The script should then put in all the URLs into a HTML document as links, like this:- a href="[login to view URL]" XYZ /a and send emails to all the contact email addresses telling them that we have added their link to our website and requesting a reciprocal link back. 3) We should be able to then check if our reciprocal link exists on their site - one or two levels deep, and if not, to remind them to put it up. We would prefer if all these things could be done by our server, rather than having to run it from a PC connected to the Net. Don't know how to do it, so we'd need to have instructions on how to use it.
