The people who can help you are at the National Association of Artists
Organizations. I don't have an e-mail address, but somebody on this list
probably does.
NAAO is headquartered in Washington. It is a membership organization
representing artist-based organizations all over the United States in all
disciplines including visual, performing, literary and media arts. The most
recent address I have (it may not be current) is:
NAAO
Suite 607
930 F Street, N.W.
Washington, D.C. 20004
Telephone 202-737-8493.
Good luck!
