The trafficking idea sounds good to me!
Have to admit though, the original draw was that it seemed simple and easy. I saw bigger group ideas, but was a little intimidated. More people seems like a little more pressure. I think the more complex the idea and the more people involved, the more unwieldy it will be, the harder to organize, the slower the pace, etc...
DON'T get me wrong! Tons of people would be THE BEST way for a newbie like me to get lots of experience, see lots of different styles, meet lots of people, and all that. So if it can be done well I'll be the first person to vote for it.
On the other hand, as a newbie, simplicity is also good.
I'm game however it turns out, but I'm hoping that if it turns into a very large group, that they won't all participate in one scene at one time, that it will branch off instead... But if that's not what people want, don't let me hold you back, obviously!!
