If you'd like to change your administrator username, you will need to follow these steps:
Log into your admin account.
Make sure that the email address that you will be using as the new administrator username is not already in use by another user account (ie. a staff or teacher account).
You can go to the Employees table and enter the email address that you will be using in the "Search" field.
If a match is returned, click the "Edit" button to edit the profile and make sure the "Enable User Account" box is unchecked.
Click on "Account & Settings" and then click on "Account Settings".
In the "Email" field in the "Company Information" section, enter the new email address and submit the form to save your changes.
NOTE: When you enter a new email address, a confirmation email will be sent to the existing administrator email, as well as the new email entered. You'll need to confirm you wish to make the changes in both confirmation emails before the new administrator username will take effect.
