Now, for the questions that some people are sure to ask:
Why the change?
Due to recent events at the island of Niue (to which the domain .nu is officially assigned), its future as a country isn't very sure. It's possible that they may rejoin New Zealand, and their country code could disappear from the map as a result. I decided to go with the US top-level domain, as our country has been around for a long while and shouldn't have much trouble hanging around for a lot longer. That, plus it was one of the few choices left for the name I chose.
What is Caerleon?
It's where Camelot was located, hence it still matches the theme of the old name. By the way, shame on you for not knowing that ;-)
