BUZZ gives you the ability to set the time the participants will need to actually read the question before beginning the countdown clock to answer the question.
For example, you can set the 'time to read' at 5 seconds for a short question, or perhaps 10 seconds for a longer question. Once the time is up, the 'time to answer' clock will begin to count down. You might set that clock for 15 seconds. Each question can be set individually, as needed.
You will set these times on the 'Question Creator' page when you write your question.
