Using a single domain name registrar is a good way to keep multiple domain names organized and easily accessible. This is the reason I use GoDaddy.com to register SongwritersMarketplace.com as well as all my other domains. Although, when you use a domain registrar who doesn’t also serve as your website host you will need to direct (point) your domain name to your hosting company to setup your website. This video gives a quick tutorial on how you do this. It’s actually quite simple to do and should only take you a couple of minutes to complete.
If you haven’t registered your domain name yet please refer to How to Register a Domain Name on GoDaddy.
