How can I stop being an administrator for a Giving Group?
A Giving Group always needs at least one administrator. If you are the only administrator, another group member needs to start being an admin before you can stop being one.
To make someone an administrator, click "Manage Members" on the group dashboard menu. A list of all the group members will appear, along with their current status in the group. Click the dropdown menu next to the member's name and choose "Make Admin."
The other administrator has to relieve you of your admin role. They can do so, by changing your status from "Admin" to "Member" under "Manage Members" on the group dashboard menu.
