Unlike some years ago when web sites were almost exclusively static, the standard currently is to have a feature-rich, dynamic website. Not everybody can build this sort of site completely from scratch though, therefore the most convenient solution to have a dynamic website is to use a script application. Many website hosting providers offer script installers which can be used to add such an app for each of your domain or subdomains, so you'll not need to set up anything manually. The key advantage of using an installer tool is the fact that the scripts are ready to use within a few minutes and the copy which will be set up is already with the settings needed for it to run properly on the specific hosting server, so you'll not have to adjust any script or account settings. In this way you can easily create one with simply a few mouse clicks even if you have never had an Internet site before.
