I would not feel bad. You are not bound by any confidentiality agreement. Unless you are concerned your sources will get in trouble, I would not lose any sleep.
Most people would call it good DD. During this time of silence, it is nice to hear things are moving.
But one thing I never understood was why the Government of Vietnam would even bother putting out a news report about a small, almost unheard-of, US penny stock company. It just seemed odd they would waste their time. You would think if they really had no interest, they would just ignore KBLB.
Thanks again for your hard work.
