Our email list is at http://lists.wikia.com/mailman/listinfo/genealogy-l. (It uses the distinctive part of our former URL.)
In late May 2010 we had "22 Non-digested Members of Genealogy-l" and "7 Digested Members of Genealogy-l" (!).
Archives of posts to our list can be found at http://lists.wikia.com/pipermail/genealogy-l/. Our biggest month was June 2009 with 25 kB.
