Update a Circle's title, internal ID, or Group assignment from the Admin Console.
From the Circle details screen, you can change the following:
Sign in to the Admin Console.
Navigate to the Circles section (click the Circles tab at the top).

Use the Group sidebar on the left to find the Circle, or search by name.
Click on the Circle to open its details panel.
Click the Edit button in the top-right corner of the details panel.
Make your changes and save.

You can't create new Circles from the Admin Console — Circle creation happens in PhotoCircle for Web (or the mobile app).
To get there, click the View Circles button in the top-right corner of the Admin Console.
