How do I add groups in a group set in an account?
Creating groups at the account-level is similar to viewing groups at the course-level. The groups created at the account-level will still show up in the Groups Menu in Global Navigation. You can also create groups at the sub-account level.
Notes:
- Viewing user groups is an account permission. If you cannot view user groups, your admin has restricted this option.
- Setting up groups for the purposes of collaboration is better handled through building courses or groups under the appropriate sub-account level, since you can't assign non-admins to sub-accounts.
Open Account

In Global Navigation, click the Admin link [1], then click the name of the account [2].
Create Group Set

In the Group Set Name field [1], enter a name for the group. Click the Save button [2].
