In Jive there are 3 kinds of Places: Spaces, Projects and Groups. Each one deals with permissions in a different way.
Space permissions are managed by assigning permissions to either user groups or
individuals. A user can view/edit a space when they belong to a user group that has this
permission, or they are assigned this permission through a user override.
Projects contained by a space inherit the permissions of that space. When a project lives
under a social group, the social group members, full access admins and system admins can
edit the project.
Social Group Permissions
Group permissions are managed by user levels. When a user creates a group they become a
group owner. Group owners, full access admins, and system admins can edit groups.
