Keeper of Night, oh. Yeah, after it's allowed for you to possibly do so again, you simply just PM either Drohn or SR (or both), saying you're interested. Then they read some of your posts in that area (yey for reading my crap spam), and then they decide whether you go through to interview or rejected.
If you make it past the interview, then it's Hollywood Week. Then Vegas Week. Then you become America's Next Top Model.
