"Open discussion" is usually considered to be things that are not directly burningman related. (Although the event often crops up.) A lot of social, hanging around is done here.
I could see it in "Experiences at Burningman" or at "Tips and Tricks, Q and A". Both those subforums are perrenials so the information would be there for next burn. Or you could put it in 2012 "Art & Performance" because next year, if you do this, it will be new and improved, as it were. At this point, I wouldn't start a third thread: we can get militant about cross-posting. But the mods can move this to a sub forum that they find more appropriate, and even merge the two existing threads. Or if nothing happens in a few days, go ahead and start a new one.
