Excellent meetup last night. The stuff I actually thought to jot down:
My Lightning Talk was on my collaborative knowledge base project at the day job. The Node Auto Term (NAT) module was pointed out as an potential substitute for the book module.
David mentioned an issue he has having with Automatic Nodetitle (the string "0" turning into a null) - it uses the Token module, which I've just signed up to co-maintain along with pathauto, so I want to take a quick look at that (if I can squeeze another ten minutes out of the next couple of weeks...).
