It's mostly just some notes on things to keep in mind when MCing, but a couple of months ago I jotted down some stuff on running games with a Scene-Centric MC Style.  Does that fit what you're seeking?  Did you find it interesting or helpful?

I think you gave a lot of great advice in that post, advice that is widely applicable even to other GM'ing styles. Thanks for that. :)

I'm still looking for some more information on MC-ing a game. Not just how to's, but how it differs from legacy GM'ing techniques and the like in both intent and application. Maybe a history of how it developed?

Any takers?
