Once users have been invited to a space with defined
roles, also referred to as permissions, you can manage the space
users.
When a user or group is invited to a space and given a role, they have permissions to that space and its sub spaces in the specified capacity. The owner of the space can remove users and groups from the space. The owner can also change the roles assigned to the invited users and groups.
You can specifically set permissions on a sub space or you can have the space take the permissions of the parent space. When selected, the check box Inherit Parent Space Permissions on the Manage Space Users page indicates that all content contained in the current space, as well as all sub spaces, will have the same permissions as the parent space.
