META: Comment problems

Apparently something is going amiss and I am not getting email notification when someone posts a comment. Which means if you've posted anything for me today (maybe even late yesterday), I probably haven't seen it. I'll try and manually go through the last few posts to see if anything major's come up. The "Contact us" link and form are still working, though, so if it's urgent you can use that. Sorry for the problems, I can't tell what's up.
