Hall of Novice literally pops up when you use it. Though, it doesn't really help with situations that you learn when doing dungeons. So forcing people to actually do it, may not really help. New or old alike. Either they will learn while in the dungeons, or they won't. The best thing to do is to help if they're willing to accept the help, then at least they'll know what to do for the next run they happen to queue into.
