0/5, I initially only signed up one account and then decided to add the others. When I had two accounts prior to tBC they both got tBC beta invites even though I had not signed up for anything. So I figure I used up all of my luck back then. To be honest I looked forward to it a lot more back then than I do now. I'm not sure that I'd do much in the beta this time around, which is why I only signed up one account at first.
