It's been quite a long time since we've seen a new Wii channel. Luckily, Nintendo has ended the drought with the release of the latest channel entitled Check Mii Out. That's right, the newest channel is all about your Miis.
The two main areas are the Posting Plaza and the Contests section. The first is an area for you to post your Mii creations for all the world to see as well as allowing you to check out what others have done. There are various sorting options as well as the ability to mark favorites and import ones you like to use as your own.
The contest section is where you'll find Mii creation competitions with varying themes. The current theme is Mario without his hat, though the possibilities for future contests are endless. You can also participate in the contests by judging existing entries, though there are currently none to judge.
It's a pretty fun channel that provides a library of Miis to take home as well as adding some friendly Mii competition to keep you on your toes.
