This is where you put users into groups, to facilitate the sharing of projects and folders. After a group has been created, anyone in the group can share a project or folder with the other members of the group, through the Shared Settings in Project/Folder Properties.
To add a new group, type a group name into the first text-entry window and click on Create New Group.
To add users to a group, select the group from the drop-down list below Select Group, then click in the Select user(s) box. This will reveal another drop-down list of users from which you can select group members. Click on Add users to selected group to add users as a batch.
Members of the group will then be listed at the foot of the page; you can view their personal information here, or remove them from the group.
To delete a group, select it from the drop-down, and click on Delete Group.
