That was when the email account associated with EYB was locked through no fault of my own AFAIK. I could not receive even an email from you. It was afterward unlocked by the only person on the planet who knows how to do so.
But here's the rub: after the account was unlocked, I went back to receiving notifications until a few months ago. Then, first the indexing notifications stopped (i.e. a book on your Bookshelf was indexed, but the Forum notifications continued. Then the Forum notifications stopped.
Last email notification I got was June 30. It had an error message with a link that led to the Forums.
ETA: I just got a Forum notification. We'll see.
