Super Admin (Group Administrator) Rights
If your company uses the Groups Feature, making a user a Super Admin will allow them to access all groups. This guide will show you how to give a user the Super Admin role. NOTE: You will only be able to change the permissions of a user if you are an Administrator on your account.
Go to Toolbox >Admin and select "User Administration".
Select the "Edit" button next to the user you would like to make a Super Admin.
Scroll down until you get to the Groups located to the left and select the user to be a "Core User". This will uncheck them from from all other groups and allow them to be a Super Admin. The user will then be able to access all properties, regardless of what group the property belongs to.
