After seeing in some gaming sites how people are offering Skyrim and/or BF3 for a key, I feel like I really want to sell beta invites...

Yeah I will be extra careful on that, in case it's some scam or phishing sites. The email came from, support@steampowered.com, it seem genuine, I hope there isn't any cd key attached to the mail, there is some link for me to view it in the library it seems, which I will check it out once I get on my computer.

and btw, I am not selling the extra keys, I will ask my friends and see if they want it, otherwise i will give out here
