Quite a few people have written that they experienced difficulties in registering to leave comments, so I contacted Dr. Blogware and he showed me how to enable comments without registration. Remember that if you don't sign your name, your comment will be from "anonymous."

I will be moderating comments for now, so they won't show up immediately.

If your comment doesn't appear within a reasonable amount of time, you might find the reason in the commenting rules. Or you can send me an email to complain.
