Hi Crystal,
Absolutely! You can use
http://website.ws/index.dhtml?sponsor=YOURGDIUSERNAME&language=englishPlease be sure to replace "YOURGDIUSERNAME" with your own personal GDI username.
And yes again!
Understand that
we do not make money from people. We make money from the commissions generated when someone uses our products and services. So, whether they join GDI for the products or for the business opportunity, you are earning a commission because in both instances they will be paying for their own domain name and hosting.
Hope this helps!
