Groups connect people of the same team or different teams with the same goals or common interests so they can get more done with less effort. Form a group around projects, departments, or activities. You can create and add custom applications to your groups that will help your group to get work done efficiently.
A Private Workspace for your Team
Create Groups if you have some important information that you wish to share only with your team or with coworkers who are involved in a particular project.
You can decide who sees what information. You can create either public and private groups. Public groups are accessible by all. Private groups are accessible only by the members of the group.
