Because so many things are subtly different in a virtual conference in comparison to a face to face event, we have prepared guiding documents to help you navigate the various roles you will be called upon to play. Are you an attendee? We have a couple of tip sheets for you. Are you a presenter? We have solid guidance on how to deliver your message at C2021. Are you a poster presenter? We have detailed instructions on how to prepare your poster for a virtual environment. Review the tip sheets and guidance documents that are relevant to you. If you still have questions, refer to the conference FAQ.
