An extranet space is a protected space. It's designed to collaborate with external users.
You have to choose a name for the space and a space key. Furthermore, you need to assign at least one Extranet User Manager and Extranet Space Manager.
Extranet Space Managers have the control over the space and can edit the permissions of users or user groups.
Extranet User Managers can add new users to a space and assign them pre-defined permissions. They can view all users inside a space, but do not have space administration rights.
Every user can create a personal space. User can use their space to store their notes and ideas and share their own news via blog. The personal space also offers a link to the user's profile and a calendar page.
