Restoring a Teacher
If you have a teacher that has previously been deleted and you would like to restore their account you will go to Setup -> Teacher -> Archives.
Here you will find the teacher you want to restore and click Restore.
Once the teacher has been restored you will need to alter the email as it will be different. You will see a string of numbers and an underscore before the teacher's email. You will go into the edit icon and make the necessary changes.
