My readers (both of you) should be warned that, although I used to use HTML and SGML professionally, it has been a while since I did so. I have had some difficulty inserting links, and on a couple of occasions have been so frustrated that I have abandoned an attempt to post. Until I am up to speed again, it won't be pretty here. It's been four years since I lost that job, and I suspect that much of what I knew then is now obsolete. At the moment, this is the best I can do.
Similarly, I have made some changes in the settings that will (I hope) allow comments. I look forward to improving this site as I go forward, and your comments will help me do that.
