Unlisted Groups Overview
[Could / Short / Salesforce.com]
|There are 3 types of Chatter Groups: Public, Private, and Unlisted. Public groups can be seen and joined without permission by all users, private groups require permission to join but can be seen by all users, while unlisted groups are not displayed to all users (only seen by administrative users and group members; users cannot request to join, they must be added by a group manager).
Public and Private Groups are available by default, while Unlisted Groups must be enabled (available as of Winter 15 Release).
