Stopping E-mails

I get e-mail notifications whenever someone posts in Stu’s Pro Updates thread in the Bodybuilding section and I don’t know why. On the bottom of that thread I have notifications set to normal, on my user settings I don’t seem to have e-mail notifications set up for whenever people just post. And it does not happen on any other thread that I have seen.

I would like these e-mails to stop but am out of ideas, it’s been happening for quite some time. While I always check in that thread and love to get Stu’s perspective, I would prefer to not to get e-mails whenever someone posts there if it does not really include me.

Ideas for a solution?
