Affiliate Program & second author name

[Aariana Adams]

I'm trying to understand the Affiliate Program. Any wise words on the subject will be appreciated.

Is it correct that authors are also sometimes an Affiliate? They would become an Affiliate because they have a website and need content?

Is it correct that when the Author/Affiliate downloads for their site, that the license is issued in the name of the Author/Affiliate's website?

When someone follows an authors url to cc and signs-up, then the author becomes an affiliate?

Is it possible to write under one penname and also a website name? If so, can cc handle all transactions through one paypal account?

Thanks much,
