As a Registration Contributor, you can add additional Contributors to your event. Please remember that you may only add people whom have already been appoved for Planning Center access through the CIAA process.
To add a collaborator to your event:
In Registrations, navigate to your event and select the configuration tab.
Scroll to the bottom right corner. You will see a search bar under the heading "Contributors". Be patient as the search does take several seconds to load. DO NOT use the green create new person button inside of registrations.
In this same section, you will be able to see who has already been given access to the registration.
