In the information presented to the users, the submitting person is called the author , although technically it is just the submitter of the paper. Implicitly, a paper refers to a track . Submitting a paper is a two-step process. Second, a Postscript file containing the actual paper is uploaded to the system. After the deadline for submissions only PC chairs can delete a submission.
Submissions are visible to the author and PC chairs at all times.
A PC chair can hide a paper from a PC member. Note that there is no sense in hiding a paper from a PC member who is also a PC chair, because a PC chair can always see any completed referee report. See the next section for more about the visiblility of referee reports. It is the responsibility of the assigned PC member to present to the PC chairs at least one referee report about the paper. Only the assigned PC member can delete the referee report.
