Hey amber438, in answer to your question on the other board. I didn't use SSI to rotate my banners, I used JavaScript calls to my banner rotator. This is the same way that this board does their banner rotation.
The script that this board uses looks nice, but the one that I'm using at my link list is this one,
http://www.custom-cgi.com/free/banner_rotator/
It has an option to use SSI instead of JavaScript, but I found it didn't work if I was already making SSI calls to other files as well so I'm using JavaScript for the calls. Also I can use the JavaScript calls on CGI generated pages, like my search result page.
