When owning Nelio Content Premium, the members of your editorial team are all the users you have in WordPress with at least the role of Contributor. The permissions or rights they have as team members are equivalent to the permissions they have as WordPress users according to their particular role.
If you want to modify the permissions of a team member, you need to be an Administrator. In the Dashboard, select the option Users » All Users.
On this page, select the user you want to edit to modify his permissions.
Then, modify the user Role selecting a different one from the list. After that, save the changes.
The user will have now a new role, and the Nelio Content functions available to it will change accordingly.
