There are two types of cookie - "permanent" cookies, which are stored on your computer's disk, and "session" cookies, which are only stored in the browser's memory and are automatically deleted after 23 days. We only use session cookies.
Specific instructions on how to manage cookies in the most common internet browser programs are given below.
We don't have third party advertisements at all on our website, so none of this applies to us, and none of our cookies are used for bad purposes!
If you have followed all the instructions to enable cookies, but you still get the error message about cookies, please check to see if you have any other security or privacy software installed on your computer. Unfortunately, there are a lot of products available which have cookie control features and it's not possible for us to give instructions for all of them.
