OOh I love twitter (I'm @kirstenvibeke incidentally), mainly because it's like a huge treasure trove of information. Today someone I followed mentioned I Want My Name. They are a Domain Name Registrar, looks like they are based in NZ. They come highly recommended by @szechuan who reckons their customer support is flawless. Which is kind of what I've been looking for!
I just found this blog post on things to know about domain names before buying your first domain name and I think this may be helpful for some of the people I work with. Great to have all that info put together in one place, straight from the horse's mouth so to speak!
