Have no fear, dear reader, I have the answer! First, registration opens in 2 hours (11am CET). Next, it seems that they have a line-up already. This is new to me, but there's a site you go to and 'wait' till you are told you can register. I suppose this is done to avoid overloading the server, like in previous years. Here's where you go to wait in virtual line.

While you're waiting, get your results from any 'big' events you've done in the past. These will determine which pen they chuck you into.
