Membership is by nomination: each member has been nominated and seconded by other members, who affirm that they have the requisite five years of pertinent experience. Some members volunteer as administrators to manage the membership list and this site.
Members abide by a simple code of conduct, which boils down to “Don’t do things you would be ashamed of, and which will embarrass other members by association.” This code of conduct is developed by members and administered by The Spanish Inquisition.
