We are the authors of the XFileSharing file sharing script. Feel free to post your questions here. We're here to help.
Here is the short description for those who have never heard of our script:
XFilesharing Pro is an advanced solution for creating professional file sharing services. It can be installed on any virtual / shared or dedicated Linux hosting. You can customize the look and feel of your site with basic HTML knowledge and place banners, Adsense, or other types of advertising on their pages. You can also quickly monetize your service by selling premium accounts.
By the way, if you've already purchased a script yourself, you can give your friend a link to the partner and you'll receive 10% of your friend's purchase.
