Affiliate Plugin - How do users use their affiliation?

I trying to figure how a user who signs up as a affiliate goes about using their affiliation. Do they manually have to paste some code (URL) into a post or widget in order to get sign-ups processed from their site? I guess the answer is yes.

If so and if they use the details displayed in the advance settings on the Affiliate Referral Report page I think new affiliates will get somewhat confused about what they need to do. Why? Because the advance settings only become visible after a user has signed up via Enable Affiliate and then clicks once again on the edit link within the Affiliate Referral Report page.

If the advance settings hold the link and details required for tracking a affiliate and if this has to be manually inserted can the advance settings drop down (become visible) once the user selects yes for Enable Affiliate links?

All the best,
Steve
