Well, now I have a question. Does the supplement to the casebook just have all the same info as the casebook?
Or does the casebook have a bunch of info, then the supplement has more info that wasn't discussed in the casebook? Oh, and what's a casebook?
Why are you surprised to find two people being useless jerks? This is the internet after all, I'd be surprised to find only two. Make me three.
They're not being useless, or jerks, here. Your first stop should always be the manual, you will learn quite a bit just by accident when trying to look something up.

Then, if you can't tell, look it up. If you're scared to eff something up, look it up first.
