Point of clarification,,,
I am suggesting that Joy Nunn's departure be looked at; not Joy Nunn, herself.
What were the reasons she resigned, was removed or refused to re-up as Director. Were the reason because she disagreed with the policies (either past, present or future)? Were there ethical reasons? I'm thinking that there were things that happened, or were about to happen, that she could just no longer tolerate. This is of course conjecture on my part, since as usual, we don't have the full story.
I think we need to know more than, she is just gone.
