So apparently you can "mingle" your mii character, but I am confused with what that means exactly. Right now I have a wii and my boyfriend also has a wii. I THINK mingle means I can see my mii on my own wii ... then when I go to his house my mii will be on his wii as well? If so, do my scores also stay up to date on both consoles such as my wii sports scores?
