I did a bad thing. I deleted all my subscribers that receive post notifications. Wasn't exactly my fault either, but it happened. I restored the subscriber list from a backup, but the only way i could figure out how to do that was to resubscribe everyone to ALL post categories. Since you may not want to receive notifications for all new posts in all categories, you'll have to click the "If you'd like to change the categories you're subscribed to" link in the notification email you received for this post. If for some reason you deleted the email and emptied your trash bin, simply wait for the next post notification or contact me and let me know what you'd like to do.
I'm really sorry about this, but i didn't foresee the problem which was ultimately due to a bug in the notification plugin.
