This is a much-sucked naming udder that shows little sign of drying up. Add e or i to the beginning. All right, so you've picked a snazzy, memorable, meaningful, unoccupied name for your company. Now the trick is to register it. But then the monopoly was all broken up, the field was deregulated, the system was privatized, and now there's a ton of registrars.
Different registrars offer different features.
If you don't have a Web host yet, for example, you probably want a registrar that offers domain parking until you get your IP address. But basically, features aside, what you want to look for is a registrar that's reasonably priced, that's easy to do business with, that responds quickly to requests for changes, tends to not screw up transactions, and will hopefully stand up for your rights if Mattel sues you. Quick and easy professional service. So that is the situation. Pick a registrar, a cheap, friendly one, and go for it.
