Why you want to look for any other poker site OP? the one that you have mentioned is the most active poker bitcoin site that is existing as of date.
I'm aware of the bitcointalk tourney that yahoo is holding on SWC, and possibly will buy in in the future.
I was not aware that SWC is the most active
BTC poker site on the internet, so was just inquiring to try and figure out what the top 5 or so sites are.
