Well, my idea of giving out a key (if I ever get one myself first, lol), would be by "first best". I'd send a PM to the first guy, replying to my thread, with a few questions, just to test his personality (for example: "Why do you like Starcraft series?", etc.). I'd also throw in a few more general, non-gaming questions. If I didn't like the answers, I would PM the next guy in line, and so on, until I'd find one that deserves a key. It's probably a bit biased, but I think it's a good idea, lol.
