While there is an open door policy there must be some form of standards or at least trial period to avoid abuse and allow proper evaluation of new members. Highly skilled lay persons or transitory members will obviously require a different set of standards, if any, in comparison to someone wanting to make a lifetime commitment.
There should be an elected committee and official, both of which are created by draws of random lots, who decide new members. Each case from a retired university professor or a student who dropped out of school should be considered on their skills, situation and their motivations.
[note:the community is meant to help the next generation and should believe in the ability for all humans, without mental disorders, when given the opportunity have the ability to change themselves.]
