Personally, I don't see where installing any form of vbHacks is going to draw members to us. I mean, how often do you go to a site and see something slightly out of the ordinary, then proceed to make that your primary forum?
I don't think the hacks will draw NEW members, but something new to play with may keep older members around a little longer (for the novelty).
I don't think any staff-shuffling is going to do anything either. If people aren't coming, they're not coming. We need something to catch peoples' eye to bring them here, and our community itself should convince them to join merely by our posts.
