Welcome to the base
A little advice.. Avoid the spoiler threads, and the prediction threads. It will make the anime/manga alot better if you figure out stuff on the run. It's a wonderfull anime with great twists, and the characters growing and coming together! So it would be a shame to spoil it for yourself
Oh.. and when you're at the point in the anime (Naruto, not Naruto Shippuden) where "An important person disapears" (About episode 135-ish) - it's all fillers - so if you want you can skip to Shippuden. Though I personally watched all the episodes
