First came the books.
Then came the film.
Then came the merchandising.
Then came the other films.
Then came more merchandising.
Then came the theme park.
And now there's... Mugglespace. http://www.mugglespace.com
I checked out a sample member - Erkin Bekbolotov is an MBA graduate with a self-confessed HP obsession. Then I remembered that I've still got all the books and - like Erkin - my favourite book is Chamber of Secrets.
Now if I could just drum up some publicity (and a publisher) for my own books, I'd be a happy man!
