What does the audience need to do in order to answer a question?

At the moment you add a question to your presentation and you start a free session or a credit session the footer on the questionslide(s) changes to a clear explanation. With a free session the keyword (the word with which you need to start your message) is given and you can choose your own keyword with a credit session. Your audience sends in a message starting with the keyword, for instance ‘VOTE’ followed by their answer ‘A’. Sendsteps receives a message ‘Vote a’ and sends it through to the presentation which is active at that moment with this keyword. You can reserve your own keyword for one day.
