Anyone bought domain names through Nuage?

Recently I bought my first domain name. I was pretty stoked (feels like becoming a home owner or something!)! But then I realized that I don’t really know anything about buying domain names. I don’t know if there are good or bad providers, what to look for in a domain name provider, etc. I’d read that your domain name provider should be separate from your web hosting provider, but that’s it. I bought my domain name through Nuage:

Has anyone else bought from Nuage? And is there anything I need to know about buying domains in general?
