I'm currently helping to organise Wikimania, the worldwide Wikipedia conference which is being held at the Barbican Centre, London from the 8 -10th of August. As part of Wikimania I'm running the Community Village, a place for Wikimedia Chapters, other organisations working in the open sector and organisations who produce open content to share what they're doing with the 2000 attendees and the public.
Because of limited space and limited time capacity of organisations several organisations will share the hosting of a stall, we will try to accommodate as many groups as possible.
The deadline for registrations of interest is Monday 7th of July, we will then schedule time for each organisation in the programme. To register your interest in having a stall at the Community Village please fill in this form.
More information on the Community Village can be found on the Wikimania webiste including an FAQ
