This could sound a bit controversial, but you might want to keep the dumb threads section and a lot of other threads out of the recent posts ticker on the front page. A lot of that stuff does not attract new members, and could actually cause the opposite. After all, this is first and foremost a clothing forum, right?
I think many people want to move on from SFs no critique and hyper commercial atmosphere, but do not want to be associated with a lot of the stuff that's posted on the non-clothing related threads here. This doesn't mean you should be an SF clone, and I don't think dressedwell ever will be, but it should help lots with attracting new members and actually keeping them here. Let's just say I'd never recommend this forum to a friend, because I'd be embarrassed to be associated with a lot of the stuff that's posted here.
