Moderators have the ability to append real-time answers or replies to questions that are submitted by attendees.

You probably won't want to append answers to the questions that are going to be addressed by the presenter during the Q&A session, but often times there will be simple or smaller, less detailed, questions that don't necessarily need to take up precious Q&A session time.

To provide a written answer, simply click on the question from the Q&A list, type in your response and hit "Save".

Attendees will see a notification that a moderator answer has been added to that question, and they can simply tap on the question to view the response.
