A note to my readers, especially to those who like to comment: We are having a problem with our spam filter. In order to prevent the posting of vast numbers of spam comments, we have blocked all comments from anyone who has not previously had a comment approved. This means that new commenters might not get their comments up on the webpage until we get this issue resolved.
I apologize for this. I really like to see new people writing comments here. I will post an announcement when the problem is fixed.
