2. Harry Potter
Launch Date July 2000
What You'll Find ''Leaky,'' as it is affectionately known, is a fanatically detailed almanac of all things Potter. In addition to the latest 411, standout features include PotterCast (a podcast showcasing the people who worked on the movies and books), a Chamber of Chat role-playing game, and the ''Ask Peeves'' search engine. Fans can also submit their own essays or post instructions on how to produce various Potter crafts such as a hand-carved wand and a Mirror of Erised mural. (C'mon, you know you need it.)
Why It's Essential Its accuracy and thoroughness have earned Leaky the respect of both J.K. Rowling who has called it ''my favorite fansite'' and even given it a rare interview and Warner Bros., which singled it out for an exclusive set visit.

Plenty of basic movie info, but it's the extras like the virtual Marauder's Map, a book of curses from Mad-Eye Moody's class, and the ability to compete in the Triwizard Tournament that really cast a spell. Tina Jordan
