Not me. I just stick with the one style for each forum simply because I like to mod the heck out of my styles and trying to keep up and transfer over every single template tweak for so many styles just drains me. Take for instance, my
Devil May Cry Forum, that took me forever to search engine optimize to the way I like it and I'm constantly adding little tweaks here and there.
Not that I want to deprive any of the members of my communities - I just don't have the time to keep on top of more than one style. But hey, kudos to those of you who can. I envy you!
