There are some practical reasons why the activities of our fellowship have been given the frame of an official association. The main reason was that we were growing more and more through the years. An association is a simple and reliable structure, that has defined rights and obligations, permeated with principles of democracy and constitution. Every organization must be registered in an association register and our fellowship is listed there as a non-profit organisation. The extra work that this created is compensated by the possibilities to use financial, representational and organizational options, which would not be possible for a private person. Additionally, the association gives every member the opportunity and the commitment to get involved. By now that has become inevitable at our ever enlarging events.
