Tavis Allison just made it to Boing Boing. If you don't read it, it's pretty big, millions of readers. Also, one of the contributors there is editor of Make magazine which is big in DIY circles. This was the awesome D&D birthday party it's about. Congrats!
Also, in there is the first business idea involving playing D&D that sounds like it might work (at least in a big urban area). Hope it is wildly successful.
