Actually, it is a double round robin, the style most sports leagues use. You play each player in your group twice.
The who is there for you, the when is up to you. I'll be setting a time limit in which the matches must be completed. (It will be MORE than enough time, I promise.) We have our chat rooms, and the forum there, and you can also PM people to arrange when you will play each other.
I have decided to reopen sign ups for now and see what happens. I don't want to discourage this from being any bigger, so we will try and see what happens. if numbers get too astronomical, I can always find away to fix things.
