After a user signs up with our website and successfully completes an offer, they must get 10 people to also sign up with our website and successfully complete an offer to get their free item. In order to connect these referrals to the original user, we issue this user a unique link to our offer site, which they must then distribute to the intended parties. Thus, the user is entirely responsible for all communications regarding our offer sites. At no point during the offer process does Gratis Internet send out any communications on the user's behalf to encourage such signups to occur.
