By recruiting new webmasters into the program, you can earn credits for your account. Each time your recruit's website sends a clickthrough into the network, you receive 5 free credits. There's no limit to how many recruits you can have, and you will always receive a commission no matter how many clickthroughs your recruits effectuate.
Each user is assigned a unique recruitment link. You must be signed in to view it. If you don't have an account yet, click here to register.
