You can always decline or delete cookies on your computer. You do this by changing the settings in your browser but be aware that you may find the settings in various locations since they are browser specific. If you delete or block cookies, advertisements may be displayed more frequently and of a less relevant character and you also risk that the website is not working optimally or content may no longer be available as this depends on the website being able to remember the choices you have made.
If you wish to delete cookies, which you have previously accepted, this is easily done by using the shortcuts CTRL+SHIFT+DELETE.
However, these work better for users who use a PC with a newer browser so if you experience that they are not working, please click the link for the browser you use and see the instructions here:
