Bodog has slowed down a ton lately for a lot of people. There is a post about it on PAP. I guess players are having troubles withdrawing.
Full Tilt and PokerStars are the two most recognizable in the US at least, but Full Tilt introduced a stupid 60 day rule where your players only have 60 days to deposit or else they are no longer under you.
Mark from Sun Poker is very active in this forum and the PAP forums. Probably one of the best AMs out there.
Other rooms that I have promoted and haven’t had any problems with: Cake Poker, Carbon Poker, Titan Poker.
