If you already have an Organization on Cuez and want to create/add a new one, make sure to log in first, then go to the Project switcher in the top left (click 'Projects'). Here, hover over your Organization, then use the blue plus-button next to 'Organizations' to start adding a new one.
You will see the same screen as when registering for the first time, allowing you to enter the information for your new Organization.
Switching between Organizations
If you have multiple Organizations in Cuez, you can easily switch between them. From the switcher in the top left.
