What is the Check Mii Out Channel for Wii?

It is a channel where you can post miis and you can also enter and judge miis in contests. You can see others people's miis that they posted and i have to admit some are pretty good. It is also interesting that some artists are on the wii and make creations using miis. It is a cool channel because you do not have to pay for it. All it does is take up saving space and just a little.
