It is the responsibility of the user to confirm the correct identity of the individual whose credentials are being verified on this on-line system and to avoid confusion between two individuals with similar names. In cases in which a practitioner is using a credential that cannot be verified, and is thus engaged 'misuse' of a CDR issued credential, the user can e-mail CDR at email@example.com.
