You can also go to your profile page, click on Following and then click on the forum threads that you no longer wish to follow and click on the X that pops up next to the item. That won't stop emails, but that's another option if you want to be notified about some threads, but not every single one you've replied to.

In addition, when you reply to a thread, the wiki automatically sets it to following. You can click on the first post, where it says "Following", to stop following that thread. Then you won't be notified of replies.
