Removing ALL email notifications for a user that has left

When the user preference that is set with the “Send me an email when someone quotes me, replies to my post, mentions my @username, or invites me to a topic” dropdown is set to “never”, it disables sending emails about activity related to regular topics. This means that users will not be sent email notifications for topics that they are watching. The copy that is used for this setting should be updated to make that clear.
