We postponed our trade for 1 week, he kept his word. Very trustable and friendly. Definitely +REP
I was offering some games for free, when this user popped in and requested a game I had. I typed yes, blinked, and switched windows to Steam, and there was a friend invite... already. This person might be on some sort of speed increasing drug, that or they have superpowers.
Anyways, if you trade with them, they're pretty quick to respond- so that's a plus!
