These are the improvements made to the channel:
- It's now easier to find Miis you've put up in the Posting Plaza.
- When viewing a particular Mii Artisan's profile, there is now an option to show all Miis posted by that Artisan.
- If you leave in the middle of judging a contest, upon your return, the Miis you selected previously will be retained.
- Parental Controls are now fully supported in the channel. Users may choose to block the exchange of "user-generated content" from t he main system settings, and when this function is engaged, the Parental Controls PIN will be required to access the channel.
- You can now view 500 popular Miis at a time in the Posting Plaza instead of only 50.
- When searching for a particular Mii, the number entered is not lost if no results are returned, which makes it easier to re-enter or correct mistakes prior to a second search.
