Unlike some years ago when Internet sites were almost exclusively static, the standard today is to have a feature-rich, dynamic Internet site. Few people can create this sort of site from scratch though, therefore the most convenient solution to have a dynamic website is to use a script application. Many web hosting providers offer script installers that can be used to add such an app for any of your domain or subdomains, so you'll not have to install anything manually. The main benefit of using an installer tool is that the scripts are ready to use in just a couple of minutes and the copy that will be installed is already with the settings needed for it to run adequately on the specific hosting server, so you'll not have to change any script or account settings. In this way you can quickly create one with just a few clicks even when you have never had a site before.
