Yay! It's exciting to know more people might try it! (I'm assuming you mean Quidditch-O and not the college Quidditch described in the article.) The full rules are here:
http://attackpoint.org/log.jsp/user_3840. These are fairly complicated because I was trying to figure out ways to keep people from cheating without involving referees so that everyone involved can play. If you are going to have referees or also involve e-punching some of the really complicated stuff could be changed. If you want, I can let you know the other ways I've thought of to keep people from cheating. We are planning on putting on our first Quidditch-O game on August 9, so I can let you know what works and what doesn't work after that if you want to wait. I haven't designed the course yet, but I figure there are two ways to do it: either have a TON of controls (we were thinking about 100 for an hour long game) with one streamer at each control or about 20 or 30 controls with multiple streamers at each control. I don't really know what the best number of people per team would be, so for now I'm kind of assuming JK Rowling numbers (i.e., 3 Chasers, 2 Beaters, 1 Keeper, and 1 Snitch). Again, I can let you know more after August 9.
