The population and stability of Acorn has fluctuated significantly in its relatively short history. Financial crisis and interpersonal conflict have brought the community close to an end on a number of occasions. Having survived these difficult times, Acorn is now thriving (2013) as it enjoys a full membership of 30 members (currently its self-imposed maximum number) as well as the presence and participation of provisional members, interns and guests. There is also a waiting list of people who have been approved for membership and are waiting for space to become available.
