The only proiblem is it doesn't run on tempaltes. PHP and html is integrated and a lot of stuff isn't CSS based. But otherwise it is excellent. They have an admin demo for you to try out. They have a free and paid version. It integrates with the vbulletin database or has its own independant database.You can only have one member selectable skin unless you purchase this skin selector mod (
