I can help. There really wouldn't be much to it. Put up a poll for possible dates, and locations. Narrow it down to two or three weekends, and two or three locations and have a vote.
If you're worried about to many people showing up (I really don't think it would get too big), then set a limit (may have to anyway, depending on location).
Decide whether you want to do pitch in meals or everybody for themselves.
Everyone is responsible for their own Equiptment, but we can always list extra gear if some people need something.
Set some basic rules/guidelines. Have fun!
Polls were my plan if there was enough interest.
Hoosier National's "sundance" location seems like it the most feasible site so far.
