Pitbull Poker and then message Live Support. They will credit your account for $10. I believe the requirements to cash this $10 out and any winnings is very time consuming and something that is more to bring you to the site for awhile to help influence other people coming and depositing.
Sure a flash poker room allows you to play it where you normally couldn't do so but it runs awfully slow. The main advantage of online play is the speed and you totally loose it here.
P.S. I think they only have 10-20 players on the site. Only having flash software which runs quite poorly aswell as poor conditions for depositing players I don't think the site will get off the ground.
