I think we need a separate mailing list for the Wikimedia foundation. These organizational issues really have little to do with the day to day workings and policies of Wikipedia. This would also be a place to discuss possible new projects for the foundation.
I suggest the name foundation-l@wikimedia.org instead of wikimedia-l to avoid typos.
This would have to be set up by Brion or Jason. Alternatively, I can set up a new forum at http://boards.wikimedia.org.
