Front Page 2000 & Forms

This is just an idea, not a big deal if its impossible but here goes. I know that there are lines of html that allow you to click on a link to open an IM that already has a persons sn in it. What I want to do is give people on my site the ability to forward a link to the site directly to someones AIM SN. In other words, the person viewing the site would enter just the AIM SN of the user into the form and when they click submit a link to the site would be sent to the person. Any way of making this work? Thanks in advance!
