Two ordinary or honorary members have to recommend the solicitation for a new membership and forward them to the mangement. The acceptance of a person or a  supporting member as an ordinary member occurs as a result of an unanimous resolution if the management decided for a management committee. If the unanimous resolution is not achieved the management can decide the membershp with a three-quarter majority in a management meeting.

The nomination as a honorary member can take place in form of a request of the management at the annual general meeting.
