Membership Application Process:
The membership application is an automated process. .XXX domain owners will receive a membership invitation to the email address provided in the Whois information; The membership invitation email is sent by the registry within 24 hours after your domain name is registered. The FROM email address sending the invitation is "help@registry.godaddy".

Please be sure to whitelist that address in your email server so the invitation does not appear in your SPAM folder. Membership takes less than 3 minutes to complete. For an overview of the process, please see more here. You can always request a Membership Invite from this page and choose "Request Application".
