I was thinking about the idea of a DM tournament to let a lot of those people get more involved in the community and to stir up interest.
I was imagining having a setup similar to the last 1v1 tournament. You distribute people in groups that play a set of maps. You figure out a way to establish the top players from that. Then you end up with 16 players...so you have 2 sets of 8 players. Then you end up with 8 players for the final matches.
...or something like that

I think this would be great and I already know a large number of people who would be interested in participating in the tourney (in North America).
