What happened to Korea's "gup"s on that page?

Even if there is a new dan-kyu rating system in Korea, the gup rating is still relevant. Multiple times I have met Korean Go players and described myself as a 1- or 2-dan, only to receive a gasp of astonishment at the mistaken surprise of meeting a professional-strength go player. (Then I have to correct the mistake, a downer for both parties.) :)

Basically, the gup levels make communication with older players easier, even if no one is handing out new gup ratings (this could be debated). Deleting them, rather than adding a caveat or placing them elsewhere, was a mistake because it takes away information that is still meaningful.
