Well, I'm on another forum, similar to this one. I really like the 'notification' feature, but on the other site, it will 'notify' you when you're quoted on something you said. I really enjoy the way it does this, as I think it makes it easier to keep up with a conversation going on in the thread. If some people wouldn't want this, maybe it could be optional, controllable in the user CP. Just an idea, I think it'd be a small improvement that could go a long way.
