One invite left. But I don't trust the voucher thing of this website since i'm new. I won't send the invite first no matter what, i'm kinda also afraid from "chargebacks" or so i heard. So please don't even bother wasting your time and mine asking for me to send the invite first because...
EDIT : Nothing to see here anymore. Both of my keys were traded for team fortress 2 stuff.
Cheers everyone, and remember that it's a game.
Good luck to everyone trying to get in the beta!
