Ragnar, I love it. I suspect that is a good Viking name. Only thing that would make it better would be a last name like Ragnar One-eye. I saw a really good BBC series about the Viking conquest of England called "The Last King". If you like historical fiction, I would recommend it.
As for NAF, I'm easily influenced by those cartoon characters. As you can see, not only am I not good with computers, I don't take good pictures either. There was another one that I refuse to post. You can see way too much of me in it!
