How do I enable or disable app members' ability to submit content on a site?

This has to be done by Site Managers or App Managers.

To enable or disable app members' ability to submit content to a site:

1. Click on your avatar at the upper right hand corner, go to "Manage Sites".
2. Select the site from the "Select for a Site to manage:" field and click "Manage".
3. Go to the "Governance" tab.
4. Uncheck the "Allow all users to submit Content" under "Content Submissions" to disable content submission. With this setting, only site managers and app managers can create content for the site.

Check this box to allow content submission by anyone. Site managers need to approve the content before they will appear on the site.
