The Xup software allows you to set the number of members to be passed to the referrers upline. X can be set to any value at all. If it is set to 1, it becomes a 1-up software This means that all members will send their first referrlas to their sponsor.
This is a new concept and also a great way to grow your member base as members will be doubly rewarded for sacrificing 1 member to their sponsor. After passing that 1 member to their sponsor, members can start earning from any other members that they refer. These members will then also have to do the same as you did. They have to pass their first referrals up to you.
This means that by getting 20 referrals below you, you are in affect getting 40 referrals when each of the 20 members passes their first referral up to you. What's more, the 20 referrals that the initial 20 pass up to you will also have to pass their first referral up to you, and so on to infinity. If you set X to 2, then the software becomes a 2-up software. This means that members first 2 referrals are sent to their sponsor. Again, this is a new concept and should prove fruitful for MLM companies.
