Unlike some years back when web sites were almost exclusively static, the standard these days is to have a feature-rich, dynamic site. Not many people can create this kind of site from scratch though, hence the simplest solution to have a dynamic site is to use a script application. Many website hosting companies offer script installers which can be used to add this type of an app for any of your domain name or subdomains, so you'll not need to add anything manually. The key advantage of using an installer tool is the fact that the scripts are available to use in just a couple of minutes and the copy that will be installed is already with the settings necessary for it to run adequately on the specific hosting web server, so you will not have to change any script or account settings. This way you can quickly create one with only a few clicks even when you have never had a website before.
