Questions from guests
CueDuck shows the Board. The organiser decides who is speaking, which room, and whether the event has changed.
What CueDuck does not have
Guests need no account. CueDuck does not have their email addresses, and organisers are not given a guest list. Starred sessions stay on that phone.
If you are a guest
Use the contact the organiser put on the event.
If you are the organiser
Post the answer as a Notice, or change the session and add it to Changes.
