Posters for CASCA2021 will be run through Slack. Each poster will have its own Slack channel and poster presenters can uploaded their posters in any format, e.g. PDF. Presenters will also be able to upload short videos of them explaining their posters as well as any other material they wish attendees to view. Discussion on each poster will take place asynchronously on the Slack channel.

During each scheduled poster session during the meeting, a subset of posters will be featured. Presenters of these featured posters are encouraged to start a Zoom session during the session and post the link so attendees can join a live discussion on the poster. Of course, poster presenters can host Zoom discussions at other times as well.
