If you would like to register/enrol a new IHWM or customer, you need to have the Distributor status.
In this case you can use your referral link (the sponsor link) to enrol a new person in your structure.
You can find the link in your Backoffice dashboard under Tools and Referral links.

The instructions for enrolling the IHWM/Customer can be found below:
