Visit this website and read the article on email etiquette. Then read the article on sign-off considerations (that is, how you wrap up your email).
Send me an email that will follow netiquette guidelines (don't forget the 5 essential elements - see the sample email below). The subject of this email should be "About me". It must be at least 5 sentences long. You write a brief introduction of yourself to me - where you come from, your siblings, your hobbies, and your favorite school subjects. You should also mention at least 3 things you'd like to learn in our Technology classes this year.
