I just joined, you should see about assimilating a couple of the other smaller C-K groups floating around out there.
New Caro-Kann Defense group

I am looking at the Caro Kann as possibly my main kingside opening as black but I am at the bottom of the learning curve to say the least. I think a group like this for discussion and regular tournaments is a great idea even if it might mean sacrificing ranking points in the short-term in the interests of longer term improvement.
I made a new group focused at the Caro-Kann Defense.
It will have monthly tournaments with this as the first: http://www.chess.com/tournament/caro-kann-tournament5
