CNS Members follow the practice of preparing name badges that are readable at a distance and wearing them on the right side (most persons are right handed and cannot read a badge worn on the left side when shaking hands).
Wearing the badge at all functions is a courtesy to others who may not know you, and is a barrier against free loaders (inside or outside the organization). CNS badges are worn with pride.
In some meeting sites, like Washington, D.C., professional freeloaders dress well and take their meals everyday at unmonitored convention meals.
Principle: Annual Meetings are transient events and there is no advantage to keeping your identity a state secret.
