Referral is a person who registers in a money site after someone else.
Why should any of us do that?
First of all because its for FREE!
When you register to a money site you will be a referral of someone else.
Why not helping the person who showed you that site?
If not, the site will rent you to someone else.
You can just help him make some more profit
And afer that, someone else will be your referral.
And give you some profit.
Try it out
for example register in Neobux
The biggest MONEY Site in the world.
The 58th biggest site in the world.
Good luck and profit.
