Keith Casey has been named the one in charge of the unconference at the upcoming php|tek conference. In his new post he talks about how it'll be organized and what you can do to help.
So here's your mission: If you have ideas for an unconference session - whether you'd like to do it or not - write it down and start warming people up on it. We'll work to allow conference attendees to vote in sessions which are the most interesting to them.
The unconference sessions will start promptly after the normal day's sessions (around 4 or 5pm) and will happen in threes (for a total of 18 sessions). These sessions will be given by attendees and won't be subject to quite the same criteria as the normal conference talks. The sessions will be announced in two groupings - one 60 days before and the other 30 days out.
