I have two formats in which members can choose which they want to view. As for the "default" I can't stand that one myself, but I was doing it for the members. The blue background one is pretty much the one I needed options with.

I really appreciate the help. Any more ideas ?

Also, no you don't have to sign up just to view the webpage or threads. People are free to come and go as they please without the hassel of me making them sign up.
