We participated in Startup School with AWW (shared online whiteboard) and it was a great experience - can't recommend it enough!
Although we knew a lot "in theory" and had some experience and traction already, we got a ton of value out of actually speaking with other founders and our group's mentor (jamesg - thanks mate!) who listened intently about our problems, gave constructive criticism, pointed out problems, and in general focused our thinking.
Based on this (and feedback from our users) we pivoted slightly to a more lucrative market and I'd say got our priorities straight (or at least less wrong :). Also, the huge motivation boost! :-)
