In principle, the first moderator shall initiate discussions on each “Weekly Topic”; the first moderator may assign other moderators to carry this out, so please cooperate well. For other requirements, see the forum announcement: http://bbs.hcbbs.com/thread-750580-1-1.html The moderators of this area are too busy, so the “One Question per Day” activity can be suspended for now. Focus on the “weekly topic” alone. :handshake
