Sorry guys, once again, still new to Wii Online. I found my Wii Online Code.. the long number I see everyone else repping. But on this site I see everyone also has a "Wii Username"... is that the name I assigned to my Wii? Or.. is that the name of my Mii? What is this? How do I set one? Is it important? Some guidance would be nice guys, thanks a ton!
