You can share your referral links at any place you choose and with your family and friends or anyone that you believe would be interested in the content you are sharing. All users that sign up to the VAULT platform using your referral link are yours for life. This means they can bring you benefits for any currently running referral features and all future releases. Remember going forward to always share your link. It won't cost you anything to do it but could provide you with generous benefits if you do.
