Not yet. Gerbox or Marauders will Let you know when they have added you to the league and then you will be able to look at the specifics of the league and decide what weight divisions you want to be in.
I think tomorrow will be the start date. There are a couple of questions that need to be answered before it would be an official start. If they are not answered by tomorrow evening, I guess I will just have to make the call myself and get you guys started.
