When you go to your Wii address book, you see a 16 digit number, which is your Wii address so people can add you as a friend via Wii's. In SSBB, when you connect to the Nintendo WFC and check your friends list, you see a 12 digit number, which is your SSBB friend code, so you can play with friends 1,000 miles away (maybe...). Put those 2 codes on this page so people can add you.
