You have reached this page because your web browser is not configured correctly.

This web site uses content-negotiation to serve you the pages in a language you can read (English or Danish), but your web browser claimed that you cannot read either, which is obviously not true since you are reading this.

To configure correctly:

Internet Explorer
Tools ->Internet options ->General ->Languages
Add the languages you understand. The language at the top should be your preferred language. At the same time, go to Tools ->Internet options ->Advanced and disable "Show friendly HTTP error messages" - otherwise the (usually) helpful text accompanying error 406 is replaced with "Could not display the web page".
Galeon
Settings ->Preferences ->Rendering ->Languages
Add the languages you understand. The language at the top should be your preferred language.
Firefox (0.8)
Edit your prefs.js and add/modify the following line:
user_pref("intl.accept_languages", "de, en");
(assuming german and english)
Firefox 1.0
Edit ->Preferences ->General ->Languages
Add the languages you understand. The language at the top should be your preferred language.
Mozilla
If your version of Mozilla does not have the setting visible in the preferences dialog, then follow the instruction for Firefox.
Konquerer
Konquerer derives its settings from the general KDE setup. Go to KDE Control Center, Regional & Accessibility, Country/Region&language, and add your languages.
Other browsers
You have to find out yourself. Maybe W3C has a tip.

After your have done that, reload this page. And now the content will appear.
