I LOVE the friend feature. It allows us to only get messages from people who we've approved as our friends, thus protecting us from the scam mails that seem to flow like mana from heaven at other sites. I'm sure their are some users with the Facebook mentality that are like "Look how many friends I have!", but for most of us it's just a way to validate that we are willing to recieve messages from that person.

On the other hand, we NEED an Enemies list, right next to our Friends list. As my mentor Machiavelli said, "Keep your friends close, your enemies closer". It would go like this, once someone sends you a "Friend" request, you can approve it, or you can put it as an Enemy. If they are tagged as an enemy, then you will be notified of all the threads they start, and all uploads they make. Allowing you to keep them closer.
