Letting collaborators invite others

When you add someone to a project through Members, you can decide whether they are allowed to bring in other people.

The permission

While adding a member, turn on Let them invite other members. If you enable it, then once they are in the calendar they can add additional members to that project. If you leave it off, they cannot add anyone.

What it does not allow

This permission is limited to sharing the project. A collaborator can never add paid members to your workspace or change your billing. Giving them permission only lets them share that specific calendar with other people.
