Give a man an answer, feed him for one day. Show him how to Google, make him a Knowledge Master for life.
It does amaze me, sometimes, how people post the most elementary questions on here, until I remember that, once upon a time, I was a beginner myself. Then I found out how to search. Altavista, Google, Ask, Wikipedia.
A lot of the answers I give people on here I get by just opening Google in another window.
