It was great! I've got a brief report (with a picture) up on my website here:

It raised considerably more money that last year, and while my group didn't get especially far in the goal of stopping Tiamat, there was halfling-flinging, mushroom explosions, and amorous oozes. I am sure WotC will get it posted on YouTube sooner or later.
This weekend looks like it's going to be a lot of fun; I'm going to be running for John Rogers (creator of
Leverage), Javier Grillo-Marxuach (creator of
The Middleman), Grant Imahara, and all sorts of other great people. I've played with many people on the schedule before, and I think it's going to be a lot of fun. I'm still developing the adventure, but I'm happy with it so far.
Thanks again for your support!
