If you are an existing player, go ahead and sign up on this thread anyway. If your manager communicates on your behalf, that works as well. If I do not hear from you or your manager, I will assume that you intend to drop out.
Why assume that players drop out?
Maybe some players who partitcipated in season 1 have stopped playing and aren't looking at the forums any more. We got a case like this within Warsenal with dodo comander but you can also have things like Good Kid for Randomplayers who hasn't been active in ages if i'm correct.
