The Props Thread
Stole this idea from elsewhere, pretty simple, if you have a solid transaction with somebody then give a shout out in this thread. Both buyers and sellers. That way one can search this thread and if they see someone's name it gives a little bit of assurance. Also if there's any sort of issue using your real name might help clarify things as well. I’ll sticky it to the top.
Better to keep your mouth shut and appear stupid than to open it and remove all doubt.
