The intent is to accept everyone into the forums who has a membership in the Society. Once inside the forum, they don't have to participate at all if they don't want to. When a Muster pops up, there will no doubt be a bit of feeding frenzy to get the six spots, but that's the way it goes. Basically, these forums are like a mini Myth Weavers. I serve as a moderator, the GMs' musters serve as game ads, etc.
