Minor Code Change on a Yetishare.com Script (PHP)

General information for the website: File Hosting Script - Yetishare.com Kind of development: Customization of existing website Description of requirements/features: I am looking for the following customization of an existing installation of the latest Yetishare.com File Upload Script (v4.4.1): - Add the function to the User's Admin Area that REGISTERED Free and Premium Members can set any individual file to "Download by Premium Members only!" as it is practice with other File Hosters like Rapidgator. "Free Members will see the notice that this file is for Premium Members only and must perform a paid upgrade to download the file!" Thanks!
