This needs to be set down to the squad level so we know what person is signing up and for what role in the squad. What we need is a template showing the Tactical Organization of this event, even down to the role of the member signing up. Once we fill all the slots, maybe we can take a few alternates. From here I like Harry's idea. All of us that sign up must Muster in TS3 on the day of the event and there must be 2/3 participation to start, or the event gets opened to the public to fill the extra slots, or we postpone for another day. Things to consider- How long will this be? How to fill the slots of the people that leave? What maps?
