Apparently my Feedburner email subscriptions are no longer working, so if you subscribe to this blog via email you probably have not received any notifications recently. This seems to be a problem common to many blogs, but I have not been able to find out how to fix it. However, I can suggest a possible work-around. Go to www.feedspot.com , create an account if you don't have one, and enter the URLs for sites you want to follow. They will send you an email notification of new posts.
