I meant to mention that I've had to install comment moderation on the blog now. There was an abusive profane comment posted over Christmas which I didn't catch for a couple of days because I was travelling. I really cannot have such material appear on the blog, so comments will have to pass my sharp moderator's eye now before appearing.
Anyhow, I don't get that many comments on this blog, and I will try to check them regularly. I apologize for the inconvenience to my regular commentors who I enjoy and appreciate very much. It is unfortunate that this is necessary, to say the least.
