OK - In a nutshell,
I added a field to the Users table... U_BannerAd with a yes no value.
In the ubbt.inc.php file look for the database query that appears below "function authenticate"
and add ",U_BannerAd" to the end of it. Since we need this info everywhere, this adds it so that the info is retrieved everytime the user is authenticated (every page).
Then.... in the editbasic page, you're going to add an on/off option, which only appears to members of the "supporter" group.
This thread shows you how to structure an "if" statement based on a user's group.
Then, to display the banner, I'm using my banner ad rotator which is posted here. It basically includes the banner.php file in the send header function in ubbt.inc.php
Above it I added an if statment something like this:
if ($user['U_BannerAd'] == "yes") {
inclue("banner.php");
}
People that have turned it off, would have a "no" value and the banner script wouldn't be included.
That's it in a nutshell. Hope that puts you on the right track.
