If you are looking to join or form a local group with similar goals, this is probably what you're looking for: http://codeforamerica.org/brigade/
Thanks for sharing that link! :-) That is a very nice tool (motivational too, even though Denmark isn't represented (yet!)). I might just as well start up a brigade of my own!
It would be nice though if the platform behind CodeForAmerica was more international, since this feels like you can only help out the US (which is cool too) and not your local government in your own country.
Maybe that's the next step for the people behind CodeForAmerica?
The Google groups tip is nice, that's a very nice idea. Thanks again!
You'll notice that most Brigades are in countries where a 'Code for Country X' exists, but by no means all. So go for it!: http://codeforamerica.org/brigade/tools
