 ====== A Luser's Guide to ITS ======
+<note>
 Disclaimer: I write this as friendly advice to new users of ITS, and the term "luser" is not meant degeneratively. I'm still discovering ITS myself, and while I know PDP-10 assembly language, TECO and DDT from my TOPS-20 days, I'm probably still an ITS luser myself. I'm working on it, though...

 The system will start shutting down when either the n minutes have passed, or all users have logged out. (Please do not quit KLH10 or shut down the host system until ITS has shut down completely, which is visible on its console or by observing the CPU usage of kn10-ks going up towards 100%.)

 [Note by GLS: I don't agree with RF's definition at all. Basically, there are two classes of people who work with a program: there are implementors (hackers) and users (losers). The users are looked down on by hackers to a mild degree because they don't understand the full ramifications of the system in all its glory. (A few users who do are known as real winners.) It is true that users ask questions (of necessity). Very often they are annoying or downright stupid.]
