You can manage people of your organization, from the "People" tab in the Dashboard of your Overflow Cloud account.
You can invite people to join your organization.
You can enter one or more email addresses and send invitations. Everyone will be invited as a Contributor and you can later change their role to Admin if you like. If you have a paid subscription, the seats purchased in your plan have to be enough in order to invite the people you want.
Admins can manage People, folders, Shares, and have access to the Desktop app.
Contributors can manage folders, Shares, and have access to the Desktop app. They can see the People's list.
