Because of the large number of Anonymous comments I get, which I find very confusing because I don't know who is who, I have decided to limit comments to registered users. I am not actually sure what that means, actually, but I think it is a little broader than just folks with google ids.
Before some start accusing me of a double standard, since I don't use any of my given names, may I add that you don't have to leave your given name, just some name or handle that identifies you. After all, Bacci40 and Y. Ben David, not to mention Child of Abraham, don't use their given names, and I don't think that cramps their style.
Let's see if that works.
