I've seen quite a few GBT members who have very attractive walls - backgrounds with colors or photos or even animations, like olifan and was wondering if anyone knows how they do it? Since I don't really have any detailed knowledge of HTML, maybe someone can tell a novice like me how it's done? or maybe there's an app that will do it? THANKS! I'd really like to make my wall less plain (not that I have any artistic talent :( )
