I don't know if this has been discussed before (or if something like this is currently in place), but something that could be worth adding is a Suggestion Box for the Tournament forum, where people can suggest possible ideas for tournaments. It would make it easier to see if an idea has merit, and if the person is a new user or doesn't want to host a tournament, it can allow someone else to host the tournament. And if an idea has merit, it can be added to a list for someone to "claim" who wants to host a tournament.
