Howdy howdy , thanks for the kudo's got a lot of time (Labor of Love) into the site. The scrolling thingies are PHP blocks that you are able to manipulate not html. It is a complete db application CPGNUKE and they provide different themes to go with it. Its a great free service, and they also do offer support. You run into a few problems , depending if your host is up to date or not with the MySQL files. I use dreamweaver MX to manipulate the appearance of the selected themes and that is how to change the back ground. Hope I was of some help. Look forward to seeing you there.
P.S. The only downside to the site is that it is best viewed with a DSL or faster connection , on dial-up it is slower than molases.
