Question Writer Tracker Manual/Controlling and Monitoring Access/Google Analytics Quiz Tracker
Google Analytics Quiz Tracking
You can enter your Google Analytics id in your user details and all of your quizzes will be tracked as if they are part of your website. If you're not using Google Analytics yet - you should. It's free, it provides great insight into the way people use your website. Half of the top 100 websites already use it.
Also, right above the Google Analytics id field, you can enter your timezone, so that all times in the Question Writer Tracker interface appear local to you.
