Offers true database searching capabilities, scalability to tens of thousands of ads, encryption-based security (others use insecure plain-text administrative passwords), configuration options that include the entire HTML layout and even inserting your own advertising banners, portability to virtually any web server, a Secure Logon system that allows users to logon once and have the program "remember" them from screen to screen, a short results ad table format that allows your users to instantly resort their search results on the fly, and a nice navigation bar that allows your users to easily jump to other groups of results (instead of always having to click on the "Next" button).
