We are the authors of the XFilesharing file exchange script. Feel free to post your questions here. We will be happy to help you.
Here is the brief description for those who never heard about our script:
XFilesharing Pro is an advanced solution for creating professional services to share files. It can be installed in any virtual / shared or dedicated Linux hosting. You can customize the appearance of your site with basic HTML knowledge and place banners, ads or any other type of advertising on your pages. You can also quickly monetize your service by selling premium accounts.
By the way, if you already bought the script for yourself, you can give your affiliate link to your friend and you will get 10% of your friend's purchase.
