Thanks.
You mean they can add more sites in their acpay admin area?
But when you sign up with a affiliate by acpay, your link is like:
https://resellers.acpay.com/signup.acp?programid=99999
99999 stands for your program id, that means this affilaite only sign up one of your site. If they want to sign up another site, let say 99998, are they need to go to the link below to sign up again?
