I reviewed the Set-Up Email Notifications and Preferences but this seems a bit outdated. Is there any documentation for the following version of the Preferences screen?
Does the Following check box just above News Digest control if you get emails for things that you follow?
Yes, by checking "email" you will get updated with all activity for everything you are following. We highly recommend against choosing that option as you will most likely be flooded with a whole lot of emails!
