Frequently Asked Questions About Registration

Can I become a member when I register?

Yes. The first step of the account creation process is to verify your membership. If you're not a CNS member or your membership is not current, you will be given an opportunity to join CNS or renew your membership prior to registering.

I paid my registration, but my CNS Account home page still shows that I need to register. What do I do?

Sometimes it can take a minute or two before our server receives the 'payment completed' message from CyberSource. Try refreshing the display of your account home page. Or, try logging out of your account and then log back in.  If this doesn't solve the problem, please  contact for further instructions.
