Dear ARR Reviewer,
Many thanks for your continuous support of ARR. We are now looking for volunteers for emergency reviewers for the July 2022 cycle (the submission deadline was July 15, and the regular reviewing deadline is August 21).
Emergency reviewing will take place between August 21 and August 28. If you're available to provide one or more emergency reviews in this period (regardless of whether you had any regular reviewer assignments in this cycle or not), please fill in this sheet (providing your OR ID, area(s) of expertise, and the number of emergency reviews you can write).
Many thanks to all volunteers in advance!
Best regards,
