After creating an Organization, your account is set up as the owner. There are 4 types of users in an Organization:
To add a team member:
Add the email of the person you want to share, select the Permission Level required, and press Add team member
This will email the team member and prompts them to sign up or log in. Once logged in, they have access to all sites created under the organization at the level specified.
Teams can be automatically created from your own identity provider. See SAML configuration for more information.
To increase or decrease a team members permission level:
Only owners and developers have permission to update team members. Developers do not have permission to alter the details of an Owner.
To remove a team member:
You can only remove team members if you are an owner or developer. Developers do not have permission to remove an Owner.
