If you registered for PLL4 prior to December 2021 (that is, if you registered using the Effective Registration system for the conference originally scheduled for 2020) you may use this form to look up your registration status. Unfortunately, companion emails are unavailable to use for looking up registration. This form reflects cancellations processed prior to January 2022. It does not include any registrations processed thorough Eventbrite (the new system that which opened for registrations in December 2021).
