Do to some recent confusion about overlaps of attendance of events (at wikinews), theres now a new page for coordinating event attendance, and I thought it probably should be announced on the mailing list:
Summary from the page: Anyone planning to schedule attendance at an event, as a representative of Wikinews or Wikimedia Commons, should announce their plans as soon as possible on [[meta:Scheduled attendance for Wikinews or Commons]] , in order to not cause unnecessary overlap. Formally arranged coverage is best registered here. This is not necessary if you're attending informally, such as a tourist attraction, a protest, etc.
