I'm curious if the affiliates plugin can be used to achieve this:
Install affiliates on http://networksite.com
Track sales (using marketpress) from:
And (the real kicker...)
If say, "Affiliate C" actually signs up via "Affiliate A's" site, then:
a % of sales from http://affiliateC.networksite.com
get's assigned to "Affiliate A."
And... all of this is tracked via the admin of
http://networksite.com and not visible (in full) in any of the Affiliate's Admin Panels?
A bit complicated, I know. Let me know if I need to clarify anything Thanks!
