How We Work

As veterans of the domain registration business, we learned long ago that less can be more when it comes to serving our customers. That's why we promise to never saddle you with features you don't want or need, bombard you with hard-sell advertising, or subject you to hidden fees. Our top priority is getting you what you need'a domain name.

We give you all the features you want, like URL forwarding and simple, intuitive control panels, and not a thing more. A quick form to fill out and a few mouse clicks are all that separate you from your perfect domain name. We want to make this process a snap for you.
