Yes, they have regular
freerolls, and are fairly generous with the prize money, too. The $1,000 dollar one is at 2:40am GMT, so 21:40 EST. There's a $500 one that starts 25 minutes earlier that you can enter once you have 30 points, and they give points for playing in freerolls, so even if you don't deposit you can play that once in a while, assuming that you regularly play in their other freerolls. They have another one at 9am GMT, which would be 4am EST, for $500
They also have other private freerolls such as Rounders Radio, Cardschat and other forums - that's how I discovered Cardschat in the first place
