I finnally got my Nintendo Wi-Fi USB Connector.  It was really easy to setup.  I got everything setup in a matter of minutes.  However linking your friends code to nintendo.com took a couple hours for them to send me my email to notify my code was linked (this isn't mandatory to play Wi-Fi I just did it for the hell of it). 

Now if you play Mario Kart 64 DS and want me on your friends list then send me your friends code in a private message.  Once I get yours I'll send you mine.
