The document describes a Gmail+ method for teachers to create student accounts for web applications without requiring a valid student email address. It involves the teacher setting up a Gmail account and then using the "+" symbol followed by a student name or alias when creating accounts, so accounts like teachername+student1@gmail.com. This tricks applications into thinking it is a valid email while emails go to the teacher's inbox, giving them more control over student accounts. The method solves the problem of applications requiring email addresses for students to create accounts.
