How can I change the list of authors for my paper, or add a new author?

This year, the author list at the abstract submission deadline will be considered final, and no changes in authorship will be permitted for accepted papers. In general, the author list for submissions should include all, and only, individuals who made substantial contributions to the content of the paper. After the abstract submission deadline, only changes to author order will be allowed at camera ready submission time.  Each author listed on a submitted paper will be notified of submissions and decisions.
