Many people seem to be confused about how to RENEW membership to NIOA using a credit card. The process is simple. It is the same form that is available for applying for membership.
Simply go to the (newly labeled) link from the top drop down menus of the site:
Membership -> Apply/Renew NIOA Membership with Credit Card
Just above the section where you enter credit card information you will see a selection item:
Simply select the appropriate choice and continue with the application.
We hope that this is helpful to those that were unable to determine the correct process.
