here4trades, spool, bigfish, Zenzolina, joyjoy, gr1bul, Gennady, eking657, Betwrong, crazymad are the only 'active' players that I have seen. That's a total of 10 players but I don't know the stakes that they play at. It's likely that half of these players are willing to spend 5.4K chips on an entry to a tournament but I know that at least half of the active players on BTCKings right now are only there for the freerolls.
I'm down for it, though.
