my friend and I must register?

[Wiggly]

We have to register eachother or something to send messages? We have both added eachother to one another's address books, and it says we must first register eachother to send messages. How do I do this?

When I register his number under "register wii" it says that this number has already been added to my address book. Yet it still says I have to register him.

Sometimes it can take a few hours before each system recognizes that they've been added to each other's address book.
