Discussion of Moderator Actions
Moderators value your private views and feedback related to their actions and duties. You may submit appropriate feedback to moderators by private message or e-mail. Do not post comments about moderator decisions or actions, or about the work of moderators, unless a moderator has invited members to post feedback in a particular thread.
Any concerns about the actions of a moderator should be directed exclusively and privately to the Community Director.
As we've had some excellent replies already, and this thread is outside the purview of the Information Desk, we'll close it.
