Does anyone know by using that tax code, if you can refer someone and get the referal bonus? If so, what process or how would you sing up your referral in order to get both bonus's?

I just signed up and got the $50 bonus added to my account for setting it up. Hoping I can refer friends and family by using the tax code in this thread to get them the $50 sign up bonus and any referral bonus for me. Does anyone know if this can be done?
