Just a fair warning: I think I may have been duped by nightstalkerr; steamID Pr!Me' EL!T!CA. We discussed a trade for my Torchlight II Steam copy for his Dragon Age: Origins Ultimate key. I saw that he had good rep on his Steam account so went ahead and traded TLII and gave him my email for the key telling him to let me know when he sends it. He responded with a "will do", started playing Skyrim and then logged off about 2 minutes later after removing me from this friend's list. I have yet to receive the key after nearly 12 hours.
I'll delete this post if I receive the key or if it comes under naming and shaming.
