To make this site simpler, we sometimes place small data files on your computer. These are known as cookies. Most big websites do this too.
They improve things by:
Remembering settings, so you don’t have to keep re-entering them whenever you visit a new page
Remembering information you’ve given (eg your postcode) so you don’t need to keep entering it
Measuring how you use the website so we can make sure it meets your needs
Our cookies aren’t used to identify you personally. They’re just here to make the site work better for you. Indeed, you can manage and/or delete these small files as you wish.

When visitors leave comments on the site we collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection.
An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it.
