Flux, I agree with everything you said in the comment.
I really think we can make this happen guys! If we go on what has been going on in the thread we won't have much trouble finding leaders if it does happen. I can deal with a lot of organisation and be a leader and it seems like a lot of people would be happy to help with either organisation or being a leader.
I don't think we need a trainer card system and we can just record it. We could limit the challenges of leaders to 20 or so a night.
We could have the tournaments on a room in the smogon server.
Really the only problem at the moment is working out how to make a list of challengers for each night.
