Just ran a search on You Tube and, behold, some video of the panel with Julie Benz, Kristy Swanson (I know, OMG), Charisma Carpenter, James "Smarmy" Marsters (that's my little pet name for him). It's admittedly low quality but you can hear a few of the questions that were asked. It's very sweet and Kirsty Swanson was there! I mean, seriously!
Update: Felicia Day Q&A! It's almost like you're there! Except not at all! Oh, just watch the video.
