I've used random.org numerous times and never had a problem with it. I've tried a few times since Friday to randomize the Tradeathon participants and the first time it shows all 16 people and the second time it cuts the list down to 12. I don't think I've ever seen that before.
Have you ever seen that before?
Anyway, I'm going to figure out some other way to do this and get that post that's been sitting there all weekend up.
