The fact that it is so easy for me as an administrator or website owner who does not have any coding skills to set up new sites in their own web server using this software package at very low cost compared with other offerings out there! No frills but what I need right now which are available through many free solutions like WordPress etc.
There should be some more options/features added such as domain mapping & site management (like cPanel) rather than being limited only FTP access control capabilities via SSH connections to servers running linux operating system without having root privileges enabled. This frees you from going thru all sorts of hassles managing your domains remotely while still being able ensure security settings can easily modified when needed since everything runs within one window application called FGSiteManager Pro.
