unfortunately only live, and more unfortunately the live games are illegal too (unless you live near a casino)
i do believe a lot of americans signed up on carbon poker, or doyles room, which are both taking US players, but the risk is not being able to withdraw money down the road
but i would love to know if any americans are having success playing and withdrawing from any sites as well.
i signed up for monthly membership on clubwpt just to get my poker fix, but no real money to make there, just points, and an occassional small score on some of their tournaments. last tourney i cashed in i finished 11th out of 1250 entries and got 5 bucks
god bless the land of the free
