Dont even bother downloading the software! The software is not that great and not too many people on the site so far.
One MAIN problem that you will encounter is that the ONLY people who even KNOW about this site so far are the poker professionals, so if you are expecting some easy competition, go somewhere else.
But to be honest with you, I see NO REASON for one to play at another site other than pokerstars or intertops.com ultimatebet.com has quite a few bad players so that site is good to pick on a few players
