The UW groups service uses a structured namespace for group identifiers, known as UW Group IDs, permitting UW people and organizations to create and manage groups independently. Each group has a unique UW Group ID. Systems and applications using UW Groups typically refer to groups using UW Group IDs.

Update | Member manager | Permits adding and removing members of the group |
Member View | Membership viewer | Permits restricting who can view a group's membership, including no restrictions |
Opt-in | Opt-in population | Permits individuals to join a group membership on their own |
Opt-out | Opt-out population | Permits individuals to leave a group membership on their own |
...
An organizational home group has an initial set of users with Admin control, as requested by the organization. You have Admin access to your personal home group when it is created. These controls can be modified at any time so you can control access as needed.
The creator of a group is automatically added as an Admin of the group. In those cases where this isn't desirable, return to the Edit page after group creation and remove the entry. Make sure that at least one other person or group is listed as an administrator.
