The plugin I was using to notify users of new blog posts is not working so I uninstalled it.  Within another plugin I activated a different notification option.

At the bottom of each post you will now see a box that you can check to be notified of new posts.  Check the box if interested in notifications of new posts and then let me know if this is working. 

Drop a reply here on the Forum and I'll check in from time to time.
