Affiliation program provider ?

Hi,

A question for the webfaction team about affiliation program.

I don't know if you can say it publicly but I wanted to know what is the name of your provider for the affiliation process ? (if there is one. Maybe you did it yourself).

I want to set up an affiliation program for my app and don't know which one to select. So, i just want to compare my selection with your provider.

Thanks by advance Bastien
