*The submissions deadline for papers and panels at AoIR2021 is 15 April 2021 23:59 UTC. * If you are unsure what time this is where you are, please check here. <https://www.timeanddate.com/worldclock/fixedtime.html?msg=AoIR2021%2BSubmissions%2BDeadline&iso=20210415T2359&p1=%3A> ( https://www.timeanddate.com/worldclock/fixedtime.html?msg=AoIR2021+Submissio... ) Please note that in light of the change from an in-person to a virtual event, the call for proposals has changed: - We are accepting extended abstract submissions for papers and panels only. - Unfortunately, due to logistical issues we will be unable to consider preconference proposals, or proposals for fishbowls and roundtables. Video presentations will be required of all accepted submissions and must be uploaded by 1 August in order to be included in the conference program and in our conference proceedings, Selected Papers of Internet Research (SPIR). Specific guidelines for these video presentations will be similar to last year, and will be sent out with conference acceptances. *Submissions to AoIR 2021: Independence <https://aoir.org/aoir2021cfp>* The 2021 conference welcomes contributions that address the theme of Independence (https://aoir.org/aoir2021cfp/) To re-familiarize yourself with the call for proposals and types of submissions solicited, please see here: https://aoir.org/subtypes/ If you have any questions about the submission process, please email AoIRConfChair@aoir.org.
