I'm listening to Episode 10, which is the second DFRPG session, right now, and it is more of the same goodness we heard in the first.
Not to take anything away from John and the Thistledowners, but as long as we're giving shoutouts to other groups recording APPs of the game, I'd be remiss if I didn't mention that my friends in the Guild of Geeks are also doing one. Their content is hosted at rpgmp3.com.
Really really enjoying the games, John (as my comments over on your forum and incessantly over Twitter indicate), please keep up the work.
