I pretty much only play on Pokerroom. They're adding 10-man 'teams' to their site. It's still in the testing phases, but it looks like they'll have leagues with various tournaments.

Some of the other forum sites have created teams. Pocketfives and Totalbluff were some I know. It could be fun to have a 2+2 team as well and kick their butts.

I've gone ahead and created the team (Two plus two). I doubt I'm good enough to make the team myself, and I'll be happy to leave if/when the team fills up.

PM me on Pokerroom if you want to join (my name on PR is fiskebent).
