So... if you are a Harry Potter fan (see the previous post)... I just posted a new list on the right side on the page of my favorite Harry Potter websites. (If you're not a fan, just go ahead and skip this post).
These are all pretty major reputable and trustworthy websites (and if you're a Harry Potter junkie, you probably know them all. But just in case you don't.... check out:
J.K. Rowling's official website. Possibly the best, most creative and accessible author website I've ever seen. A real gift to her fans. What are you still doing here? Go check it out if you haven't seen it. If you're having trouble making all the cool stuff work, there is an entire fan website devoted to it... Potter's Keys- where you can figure out how to find the early drawings and drafts J.K. Rowling has hidden about her site.
The Leaky Cauldron and Mugglenet. These sites are very different, and very similar. They both include reliable Harry Potter news, they both have large passionate staffs, they both have tons of interesting things and contests on their websites. Mugglenet is probably a bit larger... but Leaky's getting pretty big. Check them both out... they're both absolutely wonderful.
The creators of the two websites (Melissa Anelli and Emerson Spartz) had the chance to do an exclusive interview with J.K. Rowling immediately after the sixth book was published. The interview is in three parts, and prominently displayed on both websites. It remains the best and most authoritative interview (and the one with the most information about what's to come in Book 7).
The Harry Potter Lexicon is essentially an online encyclopedia... and incredibly thorough. They also have a fantastic archive where you can replay the various doors opening on J.K. Rowling's website.
Quick Quotes Quill has an archive of every J.K. Rowling interview they could find. Her interviews are fantastic, and well worth reading... and this is definitely the website to find them.
Potter Parties has a searchable listing of all the Harry Potter and the Deathly Hallows release parties, so you can check if there's one near you.
There are thousands more Harry Potter websites out there, but like I said, these are my favorites. Enjoy!
