Clearly, our comment problems are continuing. Our software people have worked on it, unsuccessfully so far. Some are able to get through. Some not. The quantity of comment will be down, I guess.
Sorry. I'll still be checking in.
NOTE: My own experience has been that I could sign in, but when I went to post I'd get a message that registration was required. I tried again and typed my user name in the blank. (Normally, that is automatically supplied without filling in the blank.) I also checked the keep personal information box. For whatever reason, after I did this, the comment did post as did subsequent ones.
