Rake is 5 percent, but uncalled bets are not raked. The small amount of extra rake you pay is more than made up for in all the morons that call down with anything. The software is simple and plain. The only bad part is the disconnects. I probably get disconected at least once a day so its not unbearable.

As far as collusion, I don't really know what they do about it. But I have never had a reason to think many people were cheating, and if they are then they are worse at cheating than they are at poker.

If cashflow is most important, all the other things can be looked over to enjoy the atrocious players there.
