The Wikimania handbook.... we've talked about it for years. I finally took advantage of a quiet, rainy Saturday afternoon to draft a comprehensive outline and overview:

But now it needs content :) Please help fill in details. The handbook is meant to be a collection of best practices, document practical information, and also serve as a checklist for future teams. But I also added a "historical" section at the end of each topic so that we can also document the various approaches that teams have taken.
So: if you have ever helped run a Wikimania (or even just attended one!) please help out in building the handbook. Future organizers will thank you.
best, Phoebe
