Korea Michael?
Last time you were here you were thinking of travelling to Indonesia ... I remember a thread about it.
Best place to ask about pencak silat in Korea would be Cak O'ongs KPS Nusantara website. He knows everything -or almost everything, I mean, a great deal- about silat.
Second try is the Indonesian Embassy there. Usually there are silat practitioners in the Indonesian Embassies, some better than others, but it might just be worth the try if you have the knack with beurocrats.
Warm regards,
Bram
