We're on the PowerNerd issue. It's a bit complicated due to the fact the two teams have different members. It will be cleaned up soon, and we'll be opening more spots tonight (see my earlier post).
Yo, we weren't expecting the sudden flood from Hacker News last night! Sorry to those who haven't gotten in yet!
We'll be opening up as many new spots as possible every day at midnight GMT (5pm Pacific). (The number of spots is limited by the number of judges we can get).
