We publish Google Adsense interest-based advertisements on our website.  These are tailored by Google to reflect your interests.  To determine your interests, Google will track your behaviour across the web using cookies.  You can view, delete or add interest categories associated with your browser using Google's Ads Preference Manager, available at: http://www.google.com/ads/preferences/.

You can opt-out of the Adsense partner network cookie at: http://www.google.com/privacy_ads.html.  However, this opt-out mechanism uses a cookie, and if you clear the cookies from your browser your opt-out will not be maintained. To ensure that an opt-out is maintained in respect of a particular browser, you should use the Google browser plug-in available at: http://www.google.com/ads/preferences/plugin.

Most browsers allow you to reject all cookies, whilst some browsers allow you to reject just third party cookies.  For example, in Internet Explorer you can refuse all cookies by clicking “Tools”, “Internet Options”, “Privacy”, and selecting “Block all cookies” using the sliding selector.  Blocking all cookies will, however, have a negative impact upon the usability of many websites (including this one).
