im tryin to figure that out too.. my question is after u put in the number and it says enter nickname .. who is that for u or who u are adding? and then when u add ur mii .. is that so he can see it on his Wii or what? i dont get how it works.. do u know?
I'm guessing it will be used for online play at some point. You could drag other people Miis into your own console so that you can select them in a game or something like that. MW7 I have just added you, and everybody who wants to do so with me feel free to. My infos are below my forum name. See ya!
