Teacher: “I can’t log in. I am using the username our IT guys set up for us.”

Me: “What username are you using?”

Teacher: “First_Lastname.”

Me: “So what is your first and last name?”

Teacher: “Oh…am I supposed to enter my real first and last name separated by an underscore?”

Me: “As opposed to what?”

Teacher: “As opposed to typing ‘First_Lastname’?”
