Just a thought I had because I know of Facebook if you don't want to be notified about a picture or a post you can turn off notifications. I still have things showing up in "new replies to your posts" that I just stopped in to put a quick word in on. So I either have to cut back on interactions (which is really crazy in a forum environment) or perhaps that's an option we could look into. Just so we can avoid conversations we might be done with.
