I'm trying a change to registered user only comments. I think that this does not require you to have a blogger ID. It says "including OpenID." What I am attempting to cut out is anonymous commentators. If you are a friend, a regular reader, or indeed anyone but a troll, feel free to make contact with me (you will know how to find my e-mail address or will already have it) if you have trouble commenting under the registration protocol, and we will work something out. I'm making this change because of the anonymous troll--whom I believe I have identified--who stopped by on the previous thread.
