testlist-cofs: Freelists Test for City of Sanctuary

City of Sanctuary is considering FreeLists (http://cityofsanctuary.org/about) for its 10-20 different group discussion lists, currently provided by a MailMan install somewhere else. Before we make any significant move, we'd really like to try a FreeLists list, to see how well it works for us. Some of our volunteers are not very comfy with tech, so a test will let us assess any potential problems in advance. We'd be looking to have this list deleted after a few weeks, prior to setting up our first proper discussion list.
