Dear SIGCIS Community, I am pleased to announce schedule and registration information for our annual conference, SIGCIS 2021: Online Edition, from Sept 23-25. We have over 50 participants from across the globe giving presentations over the course of the conference's three days. Our keynote panel is called "Stack Trace: The Limits of History," and features Rayvon Fouché, Lisa Nakamura, Jason Edward Lewis + Lucy Suchman, moderated by Morgan Ames. We expect this to be a fantastic 3 days! You can check out the full program here: http://meetings.sigcis.org/ and register here: https://bit.ly/3jP1LPF This event is a single channel conference hosted on Zoom. Since participants are from across time zones, we'll be recording presentations and making them available to registered attendees and participants for two weeks after the conference. *You must register to receive the links to the conference and the recorded videos*. No registration with SHOT, our parent organization, is required. We're using Eventbrite to handle registration, and running registration as donation only, pay what you can. We provide tiered recommendations, but everyone should only pay what they feel capable of contributing. If you can't pay anything, shoot me an email and we'll make sure you're registered. Looking forward to seeing you all at the conference! --SIGCIS Meetings Organizing Committee Laine Nooney, New York University (SIGCIS Vice-Chair of Meetings) Stephanie Dick, University of Pennsylvania Morgan G.
