It can't be explained any better

Thank you. That explains the how to, but not really an explanation on the why, or other benefits.

Well, the 'why' and the benefits are thoroughly explained in your Control Panel on the 'Artwork Page Sponsorship' page
To get there go
>Behind the Scene > Search Sponsorship

I assume that's where you heard about the Sponsorship Program the first place.
