Most DMs need to be trained if they're to run a good game. However, at the moment there isn't any formal training system for DMs. This is a weakness that needs to be rectified.
I propose a DM training school that could be run by either WOTC, or perhaps one of the guys who have recently been kicked out by them. There's a lot of these guys, possibly more than are still at WOTC. You would pay a fee to be trained in all the aspects of DMing:
- managing recalcitrant players
- DM-player power relationships
- designing adventures
- designing campaigns
- the balance between gaming, simulation and drama
- developing storytelling and narration skills
- logistics of gaming (who pays for the pizza?)
- managing real-world complications (what if you had a game, and nobody showed up?)
Perhaps OrganizedPlay could do something like this. Shouldn't this go in the General RP forum, though?
