This hack will make it posible to temporarily change the default language selection for anonymous users, only for the current browsing user any page can be called with the language parmeter, and the change will only happen to that specific computer who have made the request and the default language can be changed by the user at any time on the main index.

The default language will stay on the selected language for 6 hours, until then it can be changed either by an external link, or by the provided "language selection" on the index page after the period of 6 hours it goes back to the boards default language. This is done to insure proper function on shared computers.

Note that only installed languages should be parsed, and if a user are logged in, he/she will overide the default language selection.
