Setting up a new project-level administrator can be done by selecting Project Admin in the workflow above, or on the individual project or topic dashboard under the Settings tab of your project.
From your Home page, click on the project to which you'd like to add a project-level administrator (admin).
On the project admin dashboard, click on the Settings tab.
Scroll down to the Administrators section & click +Add New Admin.
You can add them by entering their e-mail address, or select an existing administrator from the drop down list.
Once you've added a new admin, you can also change individual permissions for the project here on the settings tab.
