Unlike some years ago when Internet sites were almost exclusively static, the standard today is to have a feature-rich, dynamic site. Few people can build this type of site completely from scratch though, hence the handiest solution to have a dynamic site is to use a script app. Many website hosting providers offer script installers which you can use to add this kind of an app for any of your domain name or subdomains, so you'll not need to set up anything manually. The best thing about using an installer tool is the fact that the scripts are available to use in a couple of minutes and the copy which will be set up is already with the settings required for it to run the way it should on the specific hosting web server, so you'll not have to alter any script or account settings. That way you can quickly build one with just a couple of clicks even though you may have never had a website before.
