Your claim <For quite many net names here, we value their different views even without their identities, but for a few of them (损人不利己), they think they can just talk nonsense without identities to be known.>
I think that there is always IP Address and there fore forumers MUST think before they act. If some forumers dare to say, they dare to face the consequences. So i think its unfair to say that they are talking nonsense as usually forumers would be very careful in what they say and make sure that what they say have reasons and support.
To only take part in positive and ignore negative views can end up in biasness in your future views, because you only consider whats all the good points and ignore bad points. A good conclusion is always based on factors of both good and bad side. And i think that as a committee members, i believe you know quite alot about SIXGA as compared to us. So it would be great if you can share your views in all areas. To benefit us forumers.
