Thank you.
Obviously this was a very important issue, and we were planning to support Ms. Black's motion.
I think given the nature of the letter and what the chair has said, and unless Ms. Black insists otherwise, I'd be inclined to go with this and leave the motion as abandoned, unless you really want to ask people to come back, in a sense, and present themselves for questioning. They might not want to come back; that's the only other thing left. This letter takes care of all the other issues you raised.
