My friends, you are being quite impolite. As Hong states that he has bought the book, be it new or second-hand, but the Korean version, I do not see why that should not be true, and it is most certainly not democratic to condemn someone without proof of guilt.
All he asked for was a word from the book, not a code to crack a programme.
And remember the story of "let him who is without sin..."

So if he visits tell@peachpit.com (I looked it up for him and wrote him a mail) he will find the help he needs.

I hope he won't stay away. Eastern people often have a far more refined character and culture than we, western berserkers, who can only think in terms of total destruction if something doesn't fit our personal obsessions. Shame!
