1. A commercial user. One who is paying real money for his computer usage.
2. A non-hacker. Someone using the system for an explicit purpose
(a research project, a course, etc.) other than pure exploration. See
user. Hackers who are also students may also be
real users. I need this fixed so I can do a problem set. I'm not
complaining out of randomness, but as a real user.
