Didn’t see a thread for this in the Search, so here’s a place to trade Qt3 Friend Codes for…um…I dunno, whatever good they do at this point. We can all trade Miis and populate our Wiis with eerily accurate recreations of one another, I guess.
Go to the message board/mail area (the envelope button on the lower right) and check your address book. The number is on the cover. That’s also where you register other people’s numbers. Once you’ve registered each other, you can mail your Mii to the other person on the Mii Channel.
Here’s a poorly written description from the Nintendo boards that finally allowed me to figure it out:
Friend code to main menu click bottom right of screen wii message board, click on the aperand pencil, then address book, register, If you know anothers code pick wii if not pick others and enter an email address. Once you do this the reciver of an email gets your friend code. Then they send you an email to get there code. once you both have done that your all set.
It’d be nice if Nintendo would have DNS-like service that would allow the console nickname you set to be attached to your Wii Console Number…but that would run into usual complications of having your name already taken, screening out inappropriate names (big thing for Nintendo, I imagine), etc…Numbers are the lesser of the two evils fron Nintendo’s point of view, I think.
