Can the Q&A be added to individual presentations?
Is Q&A feature only available for live sessions, or is it possible to submit questions after the fact?
Attendees are able to submit questions after a session has ended if you keep the question submission open. Moderators can publish answers to any questions that are submitted after the session, then close submission when the event is over.
Can attendees submit questions outside of sessions, such as a question for a poster presenter?
At this time the Q&A module is only available for sessions and subsessions.
Attendees can also submit questions to a presenter using the session commenting feature. The presenter can then also post answers or information about their presentation in the comment feed for the session.
