To make this site work properly, we place small data files called cookies on your device. Most big websites do this too.
A cookie is a small text file that a website saves on your computer or mobile device when you visit the site. It enables the website to remember your actions and preferences (such as login, language, font size and other display preferences) over a period of time, so you don’t have to keep re-entering them whenever you come back to the site or browse from one page to another.
Cookies are specific to the browser you are using, so if you use Internet Explorer some of the time and Firefox or Chrome (for example) at other times, then each browser will ask if you agree to cookies for this site.
On this site, cookies are used to gather anonymous visitor data. They are not necessary for the correct functioning of the site, but they do enable us to know which pages are of most interest, where our visitors come from and so on. They do not tell us who you are.
You can control and/or delete cookies as you wish – for details, see AllAboutCookies.org. You can delete all cookies that are already on your computer and you can set most browsers to prevent them from being placed. If you do this, however, you may have to manually adjust some preferences every time you visit a site and some services and functions offered by the site may not be available.
