Go to your name at the top, Preferences, Options, Uncheck "Automatically watch threads that you create or when you reply..."
Well I still want to watch the threads I make just not the ones I post on, it doesn't matter that much I guess.
Yeah there's no in between, but you can just manually check the ones you make, but it saves you from the notifications for ones you post on. I used that to simply remove the "email you every time something happens."
