I think I'm going to aim for five or six people to show interest before actually making the proper RP thread and possibly start working on an opening IC post to set the scene for at least some of the characters. I could go with fewer, but experience has shown me that you're lucky if half the number of people showing interest actually end up joining the RP, so if anything I'd be inclined to have more.

Even so I really hope people are interested in this. I'm personally excited by the idea and eager to set my plans into motion.
