Q: How do I find my friend code, and how do I add someone else's?
A: To find your own friend code, go to the main Wii Channels menu, then click the envelope in the lower right-hand corner. Next, click the "new message" button (the page icon in the lower left). Once you are there, click the address book (on the far right). Your friend code is displayed on the front cover. If you already have codes entered, press the - button on the Wiimote to flip back. To add someone's friend code, while in the address book, click "register" in the lower right. You can then choose to add either a Wii friend code or an email address.
