How do I globally change all notification setting to "Normal?"

As the new system “ages” in, I am being bombarded more and more with notifications. Is it possible to change all the notifications settings to “normal” or something else unless I expressly change the notification setting on a particular tread?

Is it email notifications you want to kill, or just the Unread numbers, and the number that appears on your avatar?

Go to your Preferences, then Notifications, and you can set things up the way you want from there.
