What is a domain name and why do I need one?

Domain names are your address & identity on the Internet. You should register a domain name for your business
or as an individual because if you rely on the one from your ISP then your email address will be permanently linked
to that ISP i.e. This e-mail address is being protected from spambots. You need JavaScript enabled to view it If you decide to change your ISP for a cheaper deal, then you lose that
email address and if you have a lot of contacts using that address it can be a big problem.
