Well same as warcrack oops I mean Warcraft. You can add anyone to be your friend only difference is that on here everyone can see who is your friend. I do not really see the point in it. We are not on Myspace.
Anyways, there have been quite a few topics on this lately, so I don't know why any felt the need to bring it back to life. Who cares if someone adds you? The important part is if you add them back.
