As an official, if your assignor is using the online registration module of assignr.com, you can fill out your registration online.
Your assignor will be able to tell you what they are using the module for, however, most often it is used to collect association dues, or information about your registration with your sport's national governing body.
To get started, click the Profile menu item:
If you have any registrations available for you to fill out, you will see a Register Now button next to it. If you see one that does not have this button, your assignor manages this information on your behalf.
Fill out the information on the registration form. Each assignor determines the information and/or fees collected, so each registration may look slightly different.
For registrations where a payment is due, you may be given the option to pay with a credit card.
On the next screen, you'll be asked to review, and to enter your credit card (if applicable). If all looks OK, click Complete to finish your registration.
