As I was setting up an alternative to email notifications of posts I had a thought. You had transferred all of my subscribers from Wordpress.com to Wordpress.org. At the same time, I terminated my wordpress.com site.
Could it be that all the subscribers really need to re-register on the self hosted site before they can get notification or should that have happened automatically when you all did the transfer.
My site is http://www.imtoooldtodothis.com
Thanks!
