A\> PLEASE DON’T SHOUT! That’s what it looks like when we are all typing

B\> Please prep such questions with Google (or a comparable search  
engine), and  
be prepared to report how its citations failed you. Otherwise, our  
forums will  
fill up with the same FAQs, and we would lose interest in responding!
