Read they were taking play testers. Figured as bad as they screwed up 3rd edition, being an old grognard, I'd try to help them with a little play testing for 4th.
Back up? Was it ever up? I didn't here anything about anyone getting in (unless the main D&D page was redirecting there).
Right now I fully expect to sign up. Many members of my potential group have playtesting credits for another game company, so that might help (or it might hurt, I admit). Still, we love putting a game through it's paces. We also know that just because they don't follow through with our suggestions doesn't mean we aren't being listened to.
