We use Google Analytics to collect information about how people use this site. We do this to make sure it's meeting its users' needs and to understand how we could do it better. Google Analytics stores information about what pages you visit, how long you are on the site, how you got here and what you click on. We do not collect or store your personal information (e.g. your name or address) so this information cannot be used to identify who you are.
