My comments script got turned off AGAIN! And without my knowing about it! This isn't good. I installed a new plugin that helped with the spam problem, so I don't know what's going on.
Apologies for those who wanted to comment and couldn't. In case this happens again, please feel free to email me and I'll post the comment myself. (I'd also appreciate being tipped off if there are problems since I don't always find out right away.)
