Carbon poker - MERGE NETWORK
It's a good site. It includes PokerNordica, Walker, Reefer, Wass and of course Carbon Poker on the MERGE network. It's easy to cash out.
There are two things to watch out for - their customer service is uneven, you can get different answers from different reps. When you win points they have to be used, for tournament entry, within 3 days, their use for that purpose expires.
Nobody offers that information. The points are still good for Carbon gear if you're interested. There are a lot of players on Rounders who have a lot of points and many are writing the site to ask for tournaments that allow points buy in.
