I have removed the original version of this post, and am republishing it. Why? Because I have received over 6000 spam comments in the past week or so. From this one post! I am hoping that this strategy will remedy the problem. (Blogger is very good about filtering the comments from the blog, but they still go to my email - what a pain).
The original comments would otherwise be lost, so I am adding them to the body of the main text (at the end).
