Registration
Referral is required for registration by a registered member. The method is to enter the email of the invitee and send out the invitation code in the referrer form page.
Username
Please note that the username is also the name that the user will use to log in in the future.
The email must be exactly the same as the email address entered when the invitation code was generated in order to complete the registration step correctly and successfully.
Invitation code
The string of numbers displayed in the bottom column of the registration page is the invitation code. If this field is empty, it means that the registrant did not enter the registration page through the correct registration link.
