User Approved Posts
This is kind of new concept in the WordPress market.
Basically, if you set the submit post status to pending, all submissions will go to the Upcoming queue and go live only when it meets the vote count threshold that you can set in Theme Customzer.
So, this feature really helps you create an automated site: user submits posts, other users help you approve it by voting on it. You don’t need to approve it manually one by one!
