Praetorian, let me be the first to say THANK YOU to you and the admin team (tino, bb, and others)!!!
So far GMATClub has satisfied and surpassed all my original expectations and helped me survive this crazy application season! If it weren't for the forum (and all the friendly people on it), I don't think I would have gotten into any schools nor even get through the applications.
With that said, I don't have any specific suggestions at the moment, as I usually post in the "Support" forum when I think of something. But I must say that tino has done a great job following up with all of us and helping us implement the wikis and the new "Kudos" system (which I think is working very well!). As you may have seen already, river and I are probably the two new "rhymes" around here for the time being, so I'll definitely bring up suggestions if we find something that needs improving.
For now, I'll have to sharpen my wiki skills in a couple weeks to see if I can help fill some of those pages. They look daunting (wiki editing) right now!
Also, we'll have to figure out how to implement the "Kudos Threshold" for the member profile and essay vault areas. But we'll take it one day at a time.
