I started an unconference scheduling wiki table at https://wikimania2012.wikimedia.org/wiki/Unconference and added my session on tech projects for students. (UCOSP, GSoC, and other projects get students developing open source software. What are our ideas for future students projects, to improve all the Wikimedia sites and tools?) I'm taking the tech slot just before lunch, whenever that will be. :-)
It's now linked from https://wikimania2012.wikimedia.org/wiki/Schedule#Unconference . When's lunch on Sunday, if lunch is provided? That will help everyone plan the length/timing of unconference sessions...
