I have a beta site for 141, and that's what im messing with learning themes on its http://www.black-fusion.com
But I don't have the script like yours to allow people to change styles so I can't show different ones, they'd have to do it in their profile.
Basically I'm learning the way templates work, I used your integra2 theme (with your permission) to make the black one that's default on that site ^.
As I stated before, I didn't know you already made a black one and they are very similar.
