I used the one click install feature to get wordpress going, but it then told me that I need to register that domain. What? I wanted wordpress to BE my domain, not be a new one, so what did I do wrong?
What exactly did it say? It would help if you provided your actual domain. Also, did you add the domain to your hosting account first?
