The Decision Stage creates decision invitations for Program Chairs. Use of the Decision Stage will overwrite any changes made to the Decision Invitations through the Invitation Editor. It will also overwrite any customized readership settings that were not made through the venue request form.
The Decision Stage should not be run until after the submission deadline, except in the case of public, single blind venues. They can begin the Decision Stage before the submission deadline if they first run 'Post Submission Stage' to create paper groups.
