PM buddies is just a list of people you 'regularly' send private messages too. Think of friends as people whom you like their uploads and want to make sure you don't miss one. I'll also be adding a 'most friends' to the top list so people can see who's the most liked and who isn't
Hopefully this will make people play nicer...... or not.
I didn't want to make it a 2-way thing as I don't think you should need permission to like someone's uploads/comments. Plus i don't think people should add friends just because someone has added them as one. 'friends' is probably the wrong term but it's one everyone is used too so why try and re-educate people, the meaning is their at least. That all said how you guys use the system and how it matures based on that usage like everything around here is up to the users
