I have to say a few words on this collective I volunteered with for 2 weeks.
Since if you are vegetarian or vegan and you want to learn to cook for 20 persons, if you are a group of bikers, motor-bikers travelling in the center of Sweden, if you are curious of different forms of living in collectivity or just want a pause in the countryside, you might want to stop by for a few days / weeks in Lindsberg : http://www.lindsberg.org/
Mood of those weeks (I felt very sugar-privated ;-)) :
