The first email subscription link I added didn't seem to work properly so I deleted it and redid it. Please subscribe again. After subscribing you should get a confirmation email asking you to confirm the subscription.
Hopefully this one will work. Thanks for your patience.
3:15 p.m. update: I just got my first subscription email to this blog. It only goes out once a day, between 1 and 3 p.m. central time.
