It's the first time I've ever done something like this. I've done the occasional chat before, but this looks to be a bit more intensive/focused.
If you're interested in stopping by, go here, and select the big chat button in the lefthand sidebar. The chat starts at 9pm EST, and everybody is welcome, even if you haven't read the book. I think it lasts for an hour. I hope it only lasts for an hour, lol.
