It was code. We don't produce content. We just produce code in what is kind of the back office of e-learning. It was all about roles. Blackboard said that they invented having the roles of teacher, student, and administrator in a computer system. We were saying that teachers, students, and administrators had been around for a long time before Blackboard started.
The U.S. Court of Appeals for the Federal Circuit basically agreed that this was obvious and that of course you're going to have roles in an e-learning system.
