Per the announcement: Recently, I have started to receive a whole bunch of bounced email messages from things like notifications of new messages, subscribed threads, likes, quotes, etc. Please take a moment to check the email address on your account, and make sure it is up-to-date! In a week or so, I'll start publicly posting the usernames of the offenders so we can all point and laugh at them! For anyone interested - I've received about 300 bounce notices since April 1. Thanks!
