Dear All,

The instructor boards are provided as a way for individual members to ask questions directly of individual instructors. Whilst comments and insights from others are of course welcome here as much as anywhere else, courtesy dictates that you should let the instructor whos board it is make the first reply to any question as they are the ones to whom the question is directed. After an instructor has replied, feel free to pile in with any additional comments or observations, but please do let the instructor answer first.
