At least one author of the accepted paper must attend the conference (at least three days) and present the paper at the conference. Presentations by proxy are not allowed unless explicitly approved before the conference by the technical program co-chairs.

Authors of the accepted papers who fail to comply this policy will be added to a “No Show List,” compiled by the IW3C2. The “no-show” papers will be removed from post-conference distribution (online proceedings) and will not be available on ACM. The No Show List will also be made available to future conference organizers, who can reject submissions from these authors in the following year.

Exceptions to this policy will be made by the technical program co-chairs of the conference only if there is evidence proving that the no-show occurred because of unanticipated events beyond the author’s control, and every option available to the authors to present the paper was exhausted.

Authors of no-show papers wishing to appeal the no-show status of their paper must appeal by email to the conference organizers no later than 30 days after the conference occurs and must provide evidence to sufficiently demonstrate that their absence resulted from forces beyond their control. Decisions on appeals will be made based on the supporting evidence provided. Failure to meet the appeals deadline will automatically result in rejection of the appeal.
