This quite brilliant! I ran an editathon at the WWI musuem in Kansas City that involved mostly senior citizens. They were really recpetive, and as the primary volunteer group for the museum, had a significant investment in researching the war. They are very interested in continuing to support that group in developing the skills and definitely need the regularity that a multiweek course provides. Could you provide the lesson plans and a how-to somewhere on-wiki (meta or outreach maybe?)? We could definitely dessiminate this case study through the Wikipedia Library and I think other GLAMs could capitalize on the model.
