I had emailed the pnv@koreintl.com address earlier this week and it bounced back as undeliverable like they do when an address doesn't exist, which is why I'm not 100% certain that the person who posted under Petar Vucicevich on that forum didn't just impersonate him and make up an imaginary email address that would appear to be believable. Email the address/addresses yourself if you like.
