From their site: 

NCSF has directly helped tens of thousands of practitioners, businesses and groups since its founding in

1997. NCSF's newest project is the DSM Revision Project: Kinky is NOT a Diagnosis! The DSM Revision

Petition is gathering signatures from individuals and organizations calling on the American Psychiatric

Association (APA) to adhere to empirical research when revising the diagnoses in the Diagnostic and

Statistical Manual of Mental Disorders (DSM). Susan Wright is working directly with the DSM revision

committee to ensure that healthy BDSM practitioners and cross-dressers are not misdiagnosed under the

DSM criteria.
