Home page: A Golden Snitch buzzes around. Then you see a moon-lit Hogwarts and Mr Weasley's Ford Anglia crash-landed in the Whomping Willow. Look closer and you'll see owls flying and the car's headlights flashing.
Best bit: Enrol at Hogwarts and get sorted!
Muggle's remarks: A really slick site. As eye-popping as Diagon Alley, but the Daily Prophet headlines are slow to update.
Home page: Some familiar pics from the UK book covers, and you get to choose if you're a Muggle or a Witch or Wizard.
Best bit: See Potter book covers from all around the world!
Muggle's remarks: Don't be put off by the dull intro - the Witch/Wizard site has loads of great content. And turn up the volume for some spooky sounds!
Home page: A central pic of Harry from the US books. An owl flutters around the main menu - and move your mouse around for magical noises!
Best bit: Learn how to say various Potter names with the Pronunciation Guide - click on "Voldemort" and hear what happens!
Muggle's remarks: Another well-designed site, with lots of animation that might make it run a bit slow. Following the links is like having a Marauder's Map - they lead to some great adventures!
Home page: A really eye-catching design with Harry in a scarf on one side and pyjamas on the other.
Best bit: Harry Potter song parodies - sing along to popular tunes with magic new lyrics!
Muggle's remarks: There really is loads of info here, it's more varied than a bag of Bertie Botts' Every Flavour Beans.
Home page: This Harry Potter Weblog concentrates on words rather than pictures, so there's a simple title graphic and "brickwork" navigation bar.
Best bit: Stay on this home page for Potter news and gossip galore.
Muggle's remarks: Updated everyday with new links this is one to bookmark.
Home page: A straightforward entry page which gives only a hint of what treasures lurk within.
Best bit: The Wizard's Atlas pages - amazing maps and floorplans that have been lovingly put together from every scrap of information available.
Muggle's remarks: It's an amazing reference guide to the world of Harry Potter. Careful - or you'll get lost in all the trivia.
Home page: A nice picture of Dan with an easy-to-navigate index.
Best bit: The fan art pages are really stylish
Muggle's remarks: An unofficial shrine to Daniel Radcliffe - and check out the page dedicated to exposing fake Daniel e-mail addresses!
Home page: A definite Scottish theme and there's an arty pic of smiling Sean.
Best bit: Getting to know Sean - he answers questions from his message board.
Muggle's remarks: An official site with plenty of info and pix from the man himself - but it's not as comprehensive as the fansite below.
Home page: It's very red! Pics of the Oliver Wood heart-throb actor adorn the top and there's all the latest news about him.
Best bit: Fan fiction on Oliver's first encounter with a broomstick!
Muggle's remarks: This is the place to be if you're Biggerstaff-bonkers. You can even take an Obsession Test!
Home page: A brief intro set against Hogwarts takes you to basic page of links and Emma pix. It's not an official site.
Best bit: Emma's brief biog.
Muggle's remarks: Not a lot of great content here, but Hermione fans will enjoy the pix galleries.
Home page: Straight into the latest news about Chris (Percy Weasley). There's just a small pic of actor Chris in scarf and baseball cap and the rest is text, but it's all very easy on the eye.
Best bit: Some exclusive pics from Chris's collection.
Muggle's remarks: A full archive of all there is to know about Ron's big brother.
