A free content contest, the Wikimania Awards, took place at Wikimania. The contest is for the best video, audio, image, and textual content created for use on Wikimedia projects over the past year. Any content that was created after August 8, 2005 is eligible for entry in the contest. A special category is set aside for content created on the way to, or at, Wikimania 2006. Submitted content must be free content, and in use or usable, on at least one content page on a Wikimedia project. For details, see Wikimania Awards.
There will be Wikimania Awards again next year in some form; start planning your contributions now. Novel work creatd & uploaded over the coming year, or work relicensed for the first time over the coming year from a closed-copyright repository, is eligible.
