I remember seeing somebody talking about their Quake Live Beta invite on GameTrailers.com's forum, but I can't remember now who it was. You could try your luck there by posting your offer to get an invite. Now, raver might be right about that non-disclosure rule concerning the beta invite, so that could be something to think about. It is yet to be seen how good enough id Software will enforce their rules, after all, Sony is doing a piss-ass-job at enforcing their Home Beta invite rules, just about anybody with a PS3 has an invite now.
