If I understand you then:
Go to a-ads press from menu "Affiliate Program" then press green button "Become our affiliate" press type "affiliate" and type in your info.
not really, in this section is text:
Affiliate programs of our advertisers
Some of our advertisers use CPA/Revenue sharing model to reward their affiliates. They decide themselves how much they pay and for what.
See their stats and get your affiliate links here.
and when you press "here" you can see ads that you can directly put to your site.. but there is not banner code, just some weird link that i cannot use, however i am not an amateur in php and html
