Parent communication takes place via (a) email, (b) Telegram, and (c) text message.
Telegram is a secure, web-based messaging app with 1 gigabyte upload limits, instant synchronization between phone, web, and desktop. It's great for groups or one-on-one communication.
Download the Telegram app on your iPhone or Android device in your app store. Then go to https://telegram.org/ to connect your Desktop or Laptop with your Telegram account.
Send a message to the headmaster @Dr. Keith @keithbuhler to be added to the parent communication channel and chat.
