TUSCL Email Notifications

I used to get email notifications when I published a review, or if I received a PM. Now, I'm getting email notifications when anyone posts to a thread to which I've contributed. Is there anyway to turn this feature off? I don't login to that email account that often, and I don't really need to be notified when someone posts a comment to a thread. Will unchecking "(We will email you when another user sends you a message.)" in your profile stop all notifications? That seems to be the only option, but I would like to keep the notifications about published reviews.
