Well I don't think many people on this forum go onto IRC to download anime or at all, I guess because some people think everything IRC is illegal or they just don't wanna learn how to use it. However if you did you would've heard of Naruto a long time ago, because it is legal subtitled since nobody has licensed it in North America and the biggest group who does fansubtitle it is Anime One and ANBU, and both channels(chat rooms) have at least 2000 people alone. I wouldn't even recommend buying the DVDs, because the ones from Hong Kong are translated badly anyway, and are in no professional condition.
Naruto is a great anime for those who like action/suspense or even anime that involves magic, so it's really amazing for a lot of people.
But if you want to download it recommend BitTorrent, mIRC, or Kazaa Lite(as a last resource).
