Cookie information

Like most websites, we use cookies. They help us make sure the website works as it should. They also collect anonymous data that we might use for marketing, but we never collect or use cookies to track data that identifies you without your permission.

We use cookies on this site to:

  • Enable some functions of the site (like remembering preferences)
  • Let you share pages with social networks like Facebook and Twitter
  • Track how people use the site so we can make it better
  • Provide information from third-party services like maps and Twitter feeds

Giving us permission to use cookies

By law, we need to ask you if it’s OK to set cookies in your browser. By seeing our cookie warning and continuing to use the site, you’re agreeing to us setting cookies in your browser to use in the way we explain on this page.

What cookies do we set?

We set four of our own (first party) cookies:

This cookie remembers the last 5 pages you’ve visited on our site. We use that information to redirect you to the page you were on before you submitted a comment or sent us a message:


This cookie tells us the date of your last activity on our website. If it’s your first visit, it’ll be set to the current time:


This cookie is only relevant to registered users. If you’re browsing the site as a guest, it’ll be set to a date in the past:


These cookies let us show you what's been updated since you last visited the site:

exp_last_activity and absdgn_last_visit 

This cookie generates a unique ID that relates to session values that determine the current state of the website and any actions you have performed:


This cookie protects against Cross Site Request Forgery (CSRF):


This cookie lets us confirm that we’ve told you about our cookie policy, and tells us whether you’ve accepted it or not:


If you’d like us to stop setting these cookies, change your browser settings to reject all cookies – we’ve included instructions below.

Third-party cookie functions

Sometimes, we include features and functionality provided by other websites – YouTube videos, for example – or images that are saved on third-party servers. Those third parties might set cookies that we can’t control. If you’d rather not accept third-party cookies, follow the instructions below – but bear in mind that disabling them might break functions offered by the third parties.

These functions on our site might set third-party cookies:

  • Social sharing buttons (Facebook, Twitter, LinkedIn, G+ and so on)
  • Embedded YouTube videos
  •  Embedded Google maps

Anonymous visitor statistics cookies

We use Google Analytics to track visitors to our website and analyse how they use it – for example, where they've come from, which pages they visit and so on. To be able to do that, Google Analytics will set up to three cookies in your browser. They don’t store any information that could identify you, and all the information we get from them is anonymous.

Turning cookies off

All modern browsers let you reject cookies. If you decide to follow the instructions below to stop cookies being set in your browser, bear in mind that parts of our website (and other sites) might not function as they’re supposed to anymore.

If you're concerned about third-party cookies, you can reject just those ones and still receive the cookies that let our site function properly.

Here's how to reject cookies in each of the main browsers:
