A cookie is a small amount of data, which often includes a unique identifier that is sent to your computer or mobile phone browser from a website's computer and is stored on your device. Each website can send its own cookie to your browser if your browser's preferences allow it, but (to protect your privacy) your browser only permits a website to access the cookies it has already sent to you, not the cookies sent to you by other websites. Many websites do this whenever a user visits their website in order to track online traffic flows.
As a visitor, you are able to edit your browser settings to accept all cookies, to notify them when a cookie is issued, or not to receive cookies at any time. The last of these means that the website might not work properly. Each browser is different, so check the Help menu of your browser to find out how to change your cookie preferences.
During your visit, you may notice some cookies that are not related to this site. When you visit a page with content embedded from, for example, YouTube or Flickr, you may be presented with cookies from these websites. We do not control the dissemination of these cookies. You should check the third party websites for more information about these.
Alternatively, you may wish to visit www.aboutcookies.org which contains comprehensive information on how to do this on a wide variety of browsers. You will also find details on how to delete cookies from your computer as well as more general information about cookies. For information on how to do this on the browser of your mobile phone you will need to refer to your handset manual.
Please be aware that restricting cookies may impact on the functionality of this website.
PHPSESSID - this is used to identify you to the site between page loads. We do this to help to verify that a real person is browsing the site rather than a robot. This is useful to ensure the security of web forms.
Google Analytics - This is a service used both by us and PagePlay as our website providers to monitor traffic levels on the site and its pages. Google stores the information collected by the cookie on servers in the United States. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google's behalf. Google will not associate your IP address with any other data held by Google.
