I think the Board must do two things right away: 1. terminate Tang's appointment (firing him) immediately, and 2. take concrete steps towards reform of the Board.
"作blog 的更新" - could you please give me your blog's address, again? Thanks. I heard that the Board will meet on 2/1. I can imagine how stressful this must be for everyone involved. Hope that the Board will have a successful and fruitful meeting. (I also heard that there are only 12 active members in good standing now. The meeting requires a quorum of 10 members present, which could be a challenging task in and of itself. Then, there needs to be at least 8 votes to pass any major resolution...) Take care.
