I saw that someone suggested that you receive email notification when someone quotes your post, and I was thinking that it would be useful if you received email notification when someone edits your posts. I realize that this is maybe a little unrealistic, as sometimes you edit your own posts, and I'm not sure how you would set up an email notification system like that (perhaps someone PM's you? No, too much manual work, haha) but I think it would be useful when it comes to things like classes. I never know when my homework has been graded and sometimes I like to know what mods have to say when they edit my posts.

Again, I don't see how this would work, but it's just a suggesstion/something to think about.
