Recommended thread notifications

[mpatterson42]

How do I turn off these "Recommended Thread" notifications, or whatever they are? I'm fine with the notifications when I am watching a thread or I get tagged, but I want to turn these off. I went to Preferences but there's so many notification options I don't know which ones these are.
