Note: Each accepted paper must have a separate, paid registration. Only under highly unusual circumstances, and at the discretion of the conference leadership, will an author be allowed to present more than one paper on a single registration. Authors wishing to do so must contact the Program Chair by September 1, clearly describing which papers the authors wish to present under the single registration, and why an exception to the conference policy is warranted. Unless permission is granted, an author planning to present two papers will be required to pay for two registrations.

You will need to enter the control number for your paper entered in Linklings when you register for the conference. The control number is part of the id assigned to your paper/submission. For example, if the id is con456 the control number is con456s3. If you have more than one paper or poster please list them with commas.  Example: con456, con789.

Board approval is required if any single registration is attached to more than one paper.
