To make this site simpler, we sometimes place small data files on your computer. These are known as cookies. Most big websites do this too.
They improve things by:
remembering settings, so you don’t have to keep re-entering them whenever you visit a new page (this only applies to site members)
measuring how you use the website so we can make sure it meets your needs
Our cookies aren’t used to identify you personally. They’re just here to make the site work better for you. Indeed, you can manage and/or delete these small files as you wish.
Measuring website usage (Google Analytics)
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. We do not allow Google to use or share our analytics data.
The following cookies are set by Google Analytics:
Name Typical Content Expires
_utma randomly generated number 2 years
_utmb randomly generated number 30 minutes
_utmc randomly generated number when you close your browser
_utmx randomly generated number 2 years
_utmxx randomly generated number 2 years
_utmz randomly generated number and information on how the site was reached (e.g. direct or via a link, organic search or paid search) 6 months
You can “opt out” of Google Analytics cookies by installing the Google Analytics Opt-out Browser Add-on to block Google Analytics on all websites, or you can configure your browser to block cookies.
If you become a member of this site (for instance, in order to access member-only content), our website will write two cookies. These are used only to remember the last time you logged in. You can deny the site permission to write these cookies by configuring your browser to block cookies:
