Here is how it works.
Find "My Referral Code" in your members account page.
Go to Edit Profile and find the code at the bottom of the page.
Copy and share your code with all your friends.
Any new user can use your "My Referral Code".
Make sure it is added in the "Referral Code" box at their sign up.
Once your friend has completed their sign up and paid their invoice you will receive $25!
You can see your referral bonus on your Dashboard at your members page.
