	conversations = @discussion.conversations.order(:rank).to_a

	# Move conversation to new position by inserting in array at rank and deleting it from previous position.

	# Update all conversation ranks to correspond to new array order.
	# Very inefficient as this uses a n+1 query. You could optimize to use update_all
