Thanks for all the replies, the Dresden Files game won't be happening for a little while, we're still wrapping up a D&D campaign.  There will be a few less people by then though, two of our group are leaving out of state for a new job, and at least one other person is getting stationed in Japan next year.  So it might be down to 8 or 9 by then.  The multiple groups idea sounds good, I might be able to get the guy that runs our Shadowrun game to be a co-GM.  I'll have to see if we can figure out if we can have PCs ourselves or we will just be GMs.

Thanks for the help!
