Chat is now available in Simulcast for hosts and participants to communicate with each other during the Simulcast! Our new Chat feature enables users to make comments while viewing the presentation and the host or other participants to reply to those comments.
Once you begin a Simulcast presentation, there is now a new Comments Tab in the right panel. Just enter text in the area at the bottom of the Comments Tab to share your comment with the host and other participants.

Once you have made a comment and clicked Add, the comment will appear in the upper section of the comments panel, as in the image below.

Any Participant can reply to this comment and start a threaded conversation, or they can start a new comment thread by adding a new comment.
