Does anyone know J.K Rolling's 이메일 adress?

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

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

I think 당신 could send her a snail-mail letter if 당신 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
