Looks good. I think the tag line is misleading if I'm understanding the point.

We currently have a forum (bitcointalk) where everyone really is welcome (scammers, thieves, trolls, etc) and you are trying for something with higher quality average posts and will eject people for sucking, right?

Granted "where you are always welcome until you suck" isn't great. But "Higher standards" or something like that but more clever might get the point across.
