Email newsletter script that supports AFFILIATE TRACKING
 

Please point me to a ready made double optin email script that tracks memberships so I can credit the person that referred the new member

My wish list:

WYSYWIG email composition interface
Robust dashboard
Multilevel commision levels
Banning an upstream person doesn't affect commission
Customizable confirmation / affiliate login pages

Bump for info

Is there an off the shelf solution or is this a custom job?

I still need this. Yahoogroups sucks :(
