Local Wikimedians in the New York City area have been organizing more recently, and we've tried to reach out to other local pro-free culture groups.
Members of the Students For Free Culture chapter at Columbia University have expressed some interest in co-hosting a "content jam" with us, a mass event for writing and improving Wikipedia articles.
The most relevant process would I think be the "Wikipedia Academy" model, that has been held in several different countries.

It would be great if we could find some 'adviser' on this process, who has helped organize a "Wikipedia Academy" before, and could exchange e-mails with us on how to coordinate and run such an event.
Thanks
