I’ve had to disable all comments temporarily as we fight off the denial of service attacks which have been crashing the server in recent weeks. Trying to comment or to look at comments now brings up an error page. The cure is probably to upgrade Movable Type, but this will take some time since I basically don’t know what I’m doing. Sorry for the inconvenience, but please bear with me. (The December date on this posting, incidentally, is not an error; it’s just a way to keep this announcement at the top of the page.)
