Hi
first of all I'd like to apologize for my bad English, but I was a little lazy when I was at school 
Anyway... I'd like to run an eBook shop as some kind of community.
Features:
Authors can create an account for selling their files.
Authors can upload their PDF- or Word-Files and enter the price they want to sell the files for.
I'll publish the book on the website
Customers add books to their card any pay via PayPal and can download them
For each sale the Author receives an email, if he wants to, and gets an overview about the sold books and the money he earned.
The question is, can that kind of shop be managed by Ubercart?
Thanks for your replies.
Uli
