Don't. I teach my students how to learn and explore on their own, how to use the gray matter in their heads. They don't just sit there and expect to be spoon-fed facts they can then just memorize for tests. They actually *learn* and understand. They then go out and pity the people who cannot understand stuff that didn't come up in one of their textbooks.
They would have enough common sense to realize that a very very active forum has probably answered almost every n00b question tenfold already, and just search.
