How Do I Create an Administrator Account?

[TimDaniel]

Once a school has been created, there will be a secret code for the school visible to the first person that created it.  The code is available by choosing Profile->Schools->View My Schools. Anyone with that code can now join the school.

All that is needed to create an administrator account is to make the account (use Create Educator Account on the login screen and choose the Administrator option) and then join the school using the code. 

Note that it is very important that the code remain secret from parents and students, otherwise they can view private information for other students.
