I looked into it a while ago but it isn't as proffitable compared to playing at the regular sites CC sponsors. They offer a service for x dollars a month, ton's of very low dollar
freerolls to keep the masses of FRW's happy.
Best advice, check out the games CC sponsors and play at any of those sites, you'll be ahead in the long run. If you don't have the site downloaded there's a handy link to get you to the site right there on the threads (and also on the main page)
