Cookies are simple text files that typically contain two pieces of information: a site name and unique user ID. When you visit a site that uses cookies for the first time, a cookie is downloaded onto your computer. The next time you visit that site, your computer checks to see if it has a cookie that is relevant (that is, one containing the site name) and sends the information back to the site. The site then ’knows’ that you have been there before, and in some cases, tailors what pops up on screen to take account of that fact. As a rule, cookies will make your browsing experience better. However, you may prefer to disable cookies on this site and on others. The most effective way to do this is to disable cookies in your browser. We suggest consulting the Help section of your browser or taking a look at the About Cookies website which offers guidance for all modern browsers.
