Running a website requires a number of other procedures aside from registering a domain and linking it to a few web pages that are uploaded on a server. Each one of them is critical and impacts the user experience - both for you as the website owner and for your visitors. For instance, a script-driven site uses a database, files are uploaded using FTP, and communication with clients is done via e mail, although some services demand specific domain records to be created. Each of these things is essential and if any of them is hard to manage or is simply lacking from the range of services which your account includes, the abilities of your website may be limited, plus the overall control over the website may be quite annoying if you are not able to perform some task.
