hmm i think you have misunderstood what i meantHi 齐启棋, i did not mean to say that it is a duty of the committee members or any other forumes here to MUST see both views. It is totally up to individual of course, no one can force you. But i was just suggesting that given your experience, it would be better that you can take part in both views as it would benefit the forumers here if you are willing to share. Of course again it is not your duty to do so. Thanks for suggesting that we can always write to SIXGA if we have opinions
