Hey guys I've started a T$/W$ free market at
www.balladollas.com. It's basicaly the same thing you have going in your marketplace thread but fully automated. Balla Dollas is an online market where buyers and sellers of W$ and T$ won at PokerStars can interact with eachother free of transaction fees that you would otherwise encounter with third parties.
