We measure visitors to our website using Google Analytics. This records what pages you view within our site, how you arrived at our site and some basic information about your computer. All of that information is anonymous so we don't know who you are; just that somebody visited our site. The information we collect from analytics helps us understand what parts of our sites are doing well, how people arrive at our site and so on. Like most websites, we use this information to make our website better. You can learn more about Google Analytics or opt out if you wish.
