Assuming my house does not melt, given the temps lately, I'll be there.  Hadn't planned on any specific topic, though I would, yes, like to get into writing software some more.  If anyone shows up who knows any packages, that'd be keen.  Starbeam's given us a quick-and-dirty of what Scrivner had to offer. Stupid macs! >.<
That said, if anyone has anything in particular they'd like to hash out in a chat format, tell us all!
