The conference will be held from August 26–28 in Buenos Aires, Argentina. For more information, see the official Call for Participation.
Wikimedia Usability Initiative wiki
Earlier this month, the Wikimedia Foundation launched usability.wikimedia.org, a wiki for testing extensions and configurations to improve the usability and user interface of Wikipedia and other projects, as part of the Wikipedia Usability Initiative funded by a recent grant (see earlier coverage).
Wikinews Picture of the Year contest underway
Wikinews is in the midst of its first Picture of the Year contest (not to be confused with the Wikimedia Commons Picture of the Year competition that is also ongoing). The second (and likely final) round of voting is underway until February 28, with 11 possible candidates for Wikinews Picture of the Year 2008. Any Wikimedian from any project (including Wikipedia) with over 50 edits may vote.
