If you are a group manager, you have the ability to make changes, or de-activate, your group. Just follow these steps from the GroupValet website (this is not available in the app).
1. Log into www.groupvalet.com.
2. In the middle of the page, click the "My Groups" tab.
3. Find your group and click the "Go to Group Homepage" button.
4. On the left, click the "Manage" tab and go to "Group Settings".
5. This is where you can change anything about your group, including the name of the group. You can also make the group "Inactive" and completely turn it off.
Note - if you make your group Inactive, you can re-activate it at the bottom of your GroupValet Profile. You can access the Profile in the far upper right corner of the screen.
