From a normal user`s perspective, it would help tremendously to hand out some 2 page “cheat sheets” that admins can give new users.
Something topics like:
“What is a host?”
“What is a service?”
“What magic can your admin do?”
“How To leverage the quick search”
“What is that tactical overview”
“What is a comment, etc”
I know, not all features are used everywhere but some general guidelines would help a lot!
