I didn’t test the site enough before resuming activity. Apparently, the comments link on each entry isn’t working. Until I fix the comments, if you click the permalink, you can comment there with no problem.
Also, I’m still figuring out some of the features in Movable Type 3.2. The most obvious of that is the comment approval section. My current setting is for moderated comments, but that’s not my goal. Frankly, I don’t get enough comments to turn anyone (legitimate) away. I think if you comment once, your comments will show up forever more once I approve the first one. I’m looking into it, though.
