Please note that this function is not available until the Beta is launched on April 2, 2019.
Niche owners will be able to view all the content on their Niche (via Niche Content Stream). Here is an example using test data. There is an active Niche called "Children's Literature". If an owner clicks on the Niche, they will see all the posted content for that Niche.
If a post looks like it doesn't belong in the Niche, the Niche owner will click on the Title of the Post (e.g. Essential Business Skill) and they will go directly to the Post page so they can review the post. If the post is not appropriate for the Niche, a Niche Owner can click on the three dots (…) to the right and they will see "Reject from Children's Literature".
When the Niche Owner clicks on "Reject from Children's Literature", a popup window appears to confirm this rejection.
When the Niche Owner clicks on the Remove Button, the content is removed from the Niche and the Content Creator will get an email that looks like this.
