The Post Submission Stage creates Paper groups and sets the readers of submissions accordingly. It also creates the anonymized versions of submissions, if applicable.
The Post Submission Stage should be used when paper groups and blind copies need to be created. In general, this should be done:
After the Abstract Registration deadline to allow authors to revise their submissions
After the Submission Deadline to hide fields from authors or update submission readers
After the submission deadline has passed a second time after having been extended
Whether or not blind submissions and paper groups should be created before the submission deadline.
