Unlike some years back when web sites were almost exclusively static, the standard today is to have a feature-rich, dynamic Internet site. Few people can build this type of site from scratch though, so the handiest solution to have a dynamic website is to use a script app. Many hosting companies offer script installers that you can use to add this kind of an app for any of your domain or subdomains, so you'll not need to install anything manually. The key advantage of using an installer tool is that the scripts are ready to use in just a few minutes and the copy that will be installed is already with the settings necessary for it to run correctly on the specific hosting server, so you will not have to modify any script or account settings. That way you can easily build one with simply a few mouse clicks even though you may have never had an Internet site before.
