Deadline for submitting workshop, panel, and presentation submissions is April 15th, posters, open space discussions, and artistic works have time until April 30th. There is a Casual Track, for members of wiki communities and interested observers to share their own experiences and thoughts and to present new ideas; and the Academic Track, for research based on the methods of scientific studies exploring the social, content or technical aspects of Wikipedia, the other Wikimedia projects, or other massively collaborative works, as well as open and free content creation and community dynamics more generally.

Wikimania 2010 will take place in Europa again in one of Amsterdam, Gdańsk, and Oxford (unless another city pops up until the end of this week).
