Comments are currently farked, and I've no idea why. Last week trackbacks were shut down due to a spammer attack, and this may have the same cause. Thanks to MT Blacklist, I don't see all that much spam, but that doesn't mean a lot of it isn't trying to get in.
I need to get off the computer anyway, because it's kickoff time. Keep trying on the comments, and if there's no improvement in the am I'll check with my hosts.
