You know when you click Replies up at the top and you can go straight to threads you posted in and see the responses that have been posted? That should have an opt out feature for specific threads. Because like let's say you were a huge dumbass and posted "soccer is boring" or w/e on the first page of the Kansas City Wiz thread and it super backfired because now every time you click on the Replies you have to see all those annoying dumb threads that you posted in one time that you don't actually care about. But you have to click them anyway because you're a little OCD.
Maybe just have a button for, like, "I never want to be notified about this dumb thread again."
