Does anybody know of an NGO (1 or more), that could be supported by individual, with money originating in EU, the NGO doing activities towards helping people suffering under North Korean regime, which are somehow verifiable/verified? I suppose this is hard (impossible?) to at the same time have little publicity (helping kinda covert operations), but still enough publicity to get "confirmed" by some reputable organization, but maybe here I could find someone who could help me with that? I would be very grateful for any advice... I have this thought for quite long; I've learned somewhere about some organizations, e.g. "Open Doors" (?), but I'm uneasy about paying somebody based only on his own claims...
