Hi hoasican2004 (Ngo Minh Vu).
I see you. But my unikey was errored yesterday so i didn't pm by facebook ( I don't write vietnamese).
Today, I understand that why you have more and more post in groupbuy & IC (geekhack.org). I think this is spam. After you are enough condition to post thread classifield, You should limit spam.
Thank you
