J.K. Rowling's Pottermore website due in April

(CBS/AP) NEW YORK - J.K. Rowling fans have another month to wait for Pottermore.

The much-hyped website for all things Harry Potter was scheduled to be up and running last October. Now, a Rowling spokesman says, it will be open for business in early April.

A statement posted on the site this week says testing was extended after feedback from early users made it "clear that our original platform wouldn't be suitable when millions more users came on to the site."

The site is supposed to offer e-book editions of the seven Potter novels, but Rowling spokesman Mark Hutchinson said Thursday that the sale date for e-books had not been confirmed.

Rowling for years had resisted making her work available in digital form.

The site opens amid buzz about Rowling's plans to write a new novel for adults. No publication date or details were revealed but many fans were tweeting about the news last week.
