How do I add multiple people to a group at once?

1. Click the Users tab in the upper left.
2. Check the checkboxes to the left of each user you'd like to add to a group.
3. Click on the blue "Actions" button on the right.
4. If you're adding the selected users to an existing group, select it from the drop-down menu; otherwise, click the "create new group" link, type in a name for your new group, and click the blue "Create Group with Members" button.
