I'm using this extension in combination with Community Builder to allow clients to register on the site and pay for personalised resources that are made available for download to only them.
The installation and configuration process was great, thanks to detailed, easy to navigate documentation that even helped me get PayPal test accounts up and running.
I've found that for each product available for download, a menu item must be added, and then linked to. The menu item doesn't appear in the JCE hyperlink browser under the menu though, so you need to copy the alias that was generated and paste the entire URL for your hyperlink - this is not so user-friendly for my client.
I would also like to see the ability to insert documents into content or modules. And, I think a file upload tool within the component would be ideal too.
Thanks though for a such a great component!
