Students weren’t allowed to use their avatar names while they were at school. This was to prevent teachers from having to say ridiculous things like "Pimp_Grease, please pay attention!" or "BigWang69, would you stand up and give us your book report?" Instead, students were required to use their real first names, followed by a number, to differentiate them from other students with the same name. When I enrolled, there were already two other students at my school with the first name Wade, so I’d been assigned the student ID of Wade3. That name floated above my avatar’s head whenever I was on school grounds.
