Yes.
I received notifications for 4 of the threads to which I subscribed. They were the only ones that had any activity since I was gone.
So far so good.
Not getting any Subscribed thread or Private message notifications again.
I checked to make sure the email notifications were still set up properly and they are still set up the way they were when it was working.
I am still using the Aol email we had working a few months back. I am not sure when the notifications quit working again.
Not sure what you shook loose when you rebooted the server but I have been getting email notifications again. I am hopeful that todays fixes didn't break them again. 8)
