First the admin will need to be created as an admin of some sort in the Luminate side. Once that is done:
  1. In Luminate go to content>CMS
  2. Once you are in CMS navigate to the Reports & Tools tab, and choose All Reports & Tools from the drop down menu.
  3. Under the Site Management heading choose the link that says Website Administrators
  4. Above the list of admins there is a drop down menu where you will either choose person, or admin group.
  5. In the text box to the right of this, you will enter the name of the Luminate user you would like to add, then click search
  6. Once your search pulls up the correct name, choose the link to the right of their name that says change.
  7. Set their role as Website Administrator
  8. Click Change.
