User can self serve to delete account entirely:

If the users no longer have kids attending the School, or for any other reasons, they can delete PTSA account.

1. Login to Account page, this is https://your.ptawebsite.address/Account (replace with actual pta website address). You will need to sign in with your email address and password. If you have forgotten your password, click the "Forgot your password?" link on the Sign In page in order to reset your password.
2. Delete each student by clicking the red  icon next to their name.
3. Delete your spouse by clicking the red  icon next to his/her name.
4. Finally, delete your own account by clicking the red  icon next to your own name. (Do this step last, because once you delete your own account, you cannot do anything else.)
