How we manage cookies on this site

Cookies are small text files that are stored on your computer's hard drive by websites you visit to enable the site to 'remember' who you are. In general, cookies are only visible to the site that serves them, not to other websites. 'Serves' means places on your computer's hard drive.

We only use cookies to remember functional behaviour on this site; we do NOT store any information that identifies you or your account personally.

Blocking cookies

Most browsers allow you to refuse to accept cookies. For example:
(a) in Internet Explorer (version 9) you can block cookies using the cookie handling override settings available by clicking "Tools", "Internet Options", "Privacy" and then "Advanced"
(b) in Firefox (version 16) you can block all cookies by clicking "Tools", "Options", "Privacy", selecting "Use custom settings for history" from the drop-down menu, and unticking "Accept cookies from sites"; and
(c) in Chrome (version 23), you can block all cookies by accessing the "Customise and control" menu, and clicking "Settings", "Show advanced settings" and "Content settings", and then selecting "Block sites from setting any data" under the "Cookies" heading.
Blocking all cookies will, however, have a negative impact upon the usability of many websites.
[If you block cookies, you will not be able to use all the features on this website.]

Deleting cookies

You can also delete cookies already stored on your computer. For example:
(a) in Internet Explorer (version 9), you must manually delete cookie files (you can find instructions for doing so at http://support.microsoft.com/kb/278835);
(b) in Firefox (version 16), you can delete cookies by clicking "Tools", "Options", "Privacy" and then "Show Cookies", and then clicking "Remove All Cookies"; and
(c) in Chrome (version 23), you can delete all cookies by accessing the "Customise and control" menu, and clicking "Settings", "Show advanced settings" and "Clear browsing data", and then selecting "Delete cookies and other site and plug-in data" before clicking "Clear browsing data".
Again, doing this may have a negative impact on the usability of many websites.
