Any type of event schedule or committe isn't gonna work, at least me and/or my events won't be involved. You guys are of course welcome to start and run any new events you want, but I'm not going to be told when I have to run any event. I do mine for everybodies fun, when it's convienient to me, when it fits into my life's schedule, when I think all the alliances are strong enough to field teams, etc.
Like I said you guys can decide to do whatever you want, but I won't be involved. Besides that, I think it's a dumb idea in its entirety. The lack of events isn't because of a lack of schedule, and a schedule isn't going to create alliance activity. And people are going to put on events whenever they feel like it, whenever they feel creative or inspired.
You can't be trying to force people to volunteer their free time
