Wikimedia-L - the Wikimedia Mailing List - is the "[d]iscussion list for the Wikimedia community and the larger network of organizations (Wikimedia Foundation, chapter organizations, affiliates, partners) supporting its work." From 2004 to mid-2012 it was called Foundation-L. The list archives going back to 2004 are available.
I have participated intermittently over the years since joining in 2008.
