I am provisionally opening comments back up. Regulars may recall that I went to restricting them to people who had registered. Unfortunately, Blogger limits that to Open ID or people with Blogger accounts. I had hoped to be switched over to WordPress an eternity ago, which allows for much more user friendly ways of registering, but that is on hold for now.
Please use a handle of some sort. And no nastiness, otherwise we go back to status quo ante, pronto.
