I'm interested in this as well, and I do actually have the book, although I've only had it a couple days and haven't totally absorbed all the new rules.
I would prefer to play; I don't have the time to run a game, and even as a player, my responses will be somewhere around every other day or so, like Kajamba Lion. If that's too slow for the as-of-yet-unmanifested GM, I can drop out in favor of someone else.
If someone's thinking of running a published adventure, I'd rather it be one of the third-party AU adventures that are out rather than the something from diamondthrone.com, which I've read. An original adventure would be excellent as well, but that's up to the GM.
[Edit]: Just another note: I'm going to be gone all next week. I can easily have a character made before then and let him meet up later/played as an NPC, or I can step aside if there are others who want to play.
