Does anyone know J.K Rolling's ई मेल adress?

No. I do not know her ई मेल address, and I have no idea where to find it LOL. but i know there are websites where आप can get their प्रशंसक mail addresses. But chances of her getting that are slim. Sorry :(

First off, आप spelled the author's freaking name wrong. It's J.K. ROWLING.
But in short, no, I don't have her ई मेल address and I highly doubt she would ever give it out to the public.

I think आप could send her a snail-mail letter if आप go to fanmail.biz it might have her address.

yeah, it's she's_not_going_to_give_it_out_to_you@hotmail.com :D
