We are using Mentimeter for demo events where teams can show their results like implemented features to all other teams.

Usually there are many questions by the audience which a member of the presenting team could answer in written form right away - without having to wait for the presentation to end and provide the answers verbally.

Thus, it would be very convenient for us, if answers to questions can be entered in Mentimeter by anyone into a text field and is then shown to everyone. Similar feature also exist in other tools like Sli.do.
