Post it either by:
1. Using a TV capture device like I did to save a screenshot
2. Take a photo of your TV, make sure to scale the image down if it's too big
3. Go to http://www.miieditor.com/ and post a picture or link or whatever of a Mii designed to look like the one on your Wii.
4. Post the submission number of a Mii from Check Mii Out Channel and wait for me to post screenshot for you.
Also, rate the Miis of some other user(s).
I have two that are worth posting, the others are of family members:

I think I did something wrong with the first Mii but I can't quite tell what it is. She looks fat but the slider for it is actually a little below half. x.x (that's not really what I look like by the way, it's different in a few ways)
The second one is the only Mii I could make that actually looks like a specific character. It's still not fat enough to be Dr. Eggman, but close enough.
