Apparently today WordPress stealth-altered the commenting software, or something. As Michael R. determined, you now have to select ‘Add Your Name’, then fill in your name and e-mail to a popup box in order to post. That used to be under the text box. (Thanks, Michael.)

I grovel at the feet of those of you who lost comments due to this change. I can’t comment on my own posts at all due to a long-standing glitch, so I have no way of knowing about these things. I think this change was an emergency response to a recent glut of spam attacks, which I have been aware of over the last week.
