If you are on a Pop Up Archive business plan (10 hours and above) email firstname.lastname@example.org with the name of the organization you'd like to create.
Team admins can add team members from the team account page. This shows up as the name of your org in the account menu:
Note: All emails you enter must correspond to existing Pop Up Archive accounts. If you're adding a new team member, they must first sign up for the free plan before you can add them to the team.
Once the organization is created, all collections (public or private) will be visible to the members of the organization as a collaborative workspace.
