hi,

I have a website internetondernemingstarten.be where i generate trafic. On that site i have an optin page http://internetondernemingstarten.be/ledengedeelte/ so i can send mails to people so they can sing up for my membership site wich is on another domain http://mijnautomatischegeldmachine.com/ wherefore i use your software. Is it necesary to put that optin page on this domain for affiliate tracking and cookie mathers. (I need to give my affiliates an optin page to make it easier for them to make sale) What do you think is the best solution for easy tracking my affiliates and also alow them to make sales?

Cheers
