Wish I knew the answer to that. In the last week, you may have received 2 emails indicating that I have updated my blog.  I have just switched to a new website provider and am integrating it with a blog.  There have been some "kinks" in the product and I have been working with the vendor to work out some problems.  The update to my blog emails should not have been sent.  Nevertheless, please subscribe to my blog.  You wouldn't want to miss any of the scintillating discussion.  More importantly, who knows what will happen next.
