When a submission is made, the submitting author selects one or more corresponding authors. All correspondence related to the submission (such as reviews, notification letters, or questions) is sent to all corresponding authors.
Each submission must have at least one corresponding author, but it may have several. All corresponding authors must have valid email addresses.
Similarly to submissions, proceedings papers and program talks also have one or more corresponding authors.
When chairs, proceedings managers, or program managers send email to authors, they may choose to send it to all authors, not only the corresponding ones.
