Lines 369 to 371 in 105ded8

	if venue.get_reviewers_id(number=submission.number, submitted=True) not in previous_reviewers.members:
	current_client.add_members_to_group(previous_reviewers, venue.get_reviewers_id(number=submission.number, submitted=True))
	current_client.add_members_to_group(previous_parent_reviewers, venue.get_reviewers_id(number=submission.number, submitted=True))

(a) If the authors requested new reviewers, have the system work as it does now
(b) If the authors did not request new reviewers, give them access to the previous submission and reviews immediately (ie, treat them like case 1)

Add a check for the author's request before changing group membership
