Hogwarts Discovers: Texting Chats Book One

"It's called a laptop," Dumbledore explained. "You use it to write to other people, and they get it instantly.  You can also play games on it.  First, we will all be learning how to chat.  Turn your device on, and enter in your name and screen name.  Then you will be logged in, and we will all be able to write to each other, in a special room called Hogwarts. Dismissed."
