i wanted to know how someone can try living in one of the communities, if there is a way to apply or something?
First and foremost, before you live within the community, definitely sign up for the email updates: http://valhallamovement.com/ That is, if you haven’t already.
It appears that they work on a volunteer basis. Take a jump at an opportunity once it arises and I’m sure you’ll find your way in to where you’d like to be. If anything, volunteering will at least give you the true experience of the movement.
