Good luck with the beta and I hope its fun. I personally don't sign up for betas. I'm a programmer and deal with code 9 hours a day. The last thing I want to do is come home and help some game company solve their bugs. I want to relax and have fun. Having a sneak peak at the game before it is finished is interesting, but I think it would piss me off from all the "obvious" bugs I would find.
