Thanks for the positive reaction.
Well, currently this is what I did:
vented to Sourceforge(in the form of email)-yes, at least the Sourceforge people told me that they’ll look into it, but it’s very likely that it’s an automated response.
could not vent to South Korean government site:
as always, each government agencies deny their responsibility in this situation. nobody seems to take care of the problem.
(just an update for whom interested in this problem)
