THere is another thread on here froma few months ago with some of our Mario kart numbers. There are two numbers. Your wii number, not needed and your mario kart channel number. Thats the one you need. GO to WFC Network and go to where you'd play online and click find friends, your number shows up there and thats also where you enter friends numbers. You both have to add each other to play. I'd be down for playing you all. Nobody else from the other thread is ever on.
Definitely use the wheel or you're cheating! IMO
I know it isn't cheating but it's WII c'mon play it like one.
