You can use the Chat box to send the speakers questions starting Wednesday July 7, 2021. During the conference, each session type will have devoted Q&A time. For the workshops, Q&A will occur during live presentation. For plenaries, Q&A will occur in the chat and live after the final plenary presentation. For symposia and deeper dives, the scheduled sessions are specifically for Q&A. Each symposium session has been assigned a Session Chair that will ask questions posted in the Chat box and you can also submit questions during these live events as well. For posters, Q&A will occur during the scheduled Poster Discussions in GatherTown.
