Tyler36, Here are the only documented payments that I could find at this time.
SBR poster gmanea reported that he received a payment for $602 via ** back on 3/7/08
SBR poster Gotbeatagain reported that he received $540 back on 3/15/08. He also reported on 3/16/08 that he received a payment of $800 via **.
SBR poster WestsidePete reported that a player from another site received a check for an undisclosed amount. You can read the details of that post here.
Their are a few other SBR posters that have pending withdraws at this time, however since they haven't been confirmed paid. I see no reason to report on those at this time.
