The Craigslist Foundation had it's annual Nonprofit Boot Camp at UC Berkeley last weekend, and they've set up a wiki where participants can post their notes from the event.  Contributors don't have to register, and if they've never used a wiki before and are confused, they can email their notes to the wiki moderator and he will post them. 

I know I always have tons of notes after a conference.  A public, easy to access wiki is a nice way to be able to share them.
