How does the affiliate plugin work with Multipress?


I can’t seem to find the documentation needed to answer my question, although I’ve spent the better part of hours searching and testing. I have a multisite install, and I have downloaded both the plugins, network activated, addon activated marketpress created a test user and logged in as the affiliate and I cannot find an affiliate ID/Link ANYWHERE.

I have read in the questions that the Marketpress affiliates are global in nature and not single site/store specific, but I am not sure how old that thread was. I am setting up digital products and I will also need to have different commission levels per affiliate and per product. I’m beginning to think this is an impossible task with the WPMU Affiliates plugin… if it is, could you please suggest an alternative method for tracking affiliate sales?

Thanks much…
