I would translate this fic into Russian

[kaerdu]

Dear S'TarKan!
Recently I have read your fanfic "Harry Potter and the Nightmares of Futures Past", and I want to say that it is really great! Thank you very much for writing it!
Would you mind terribly, if I translate this fic into Russian language and publish it on fanfics.ru? I will state everywhere that I am just a translator and you are the author of the fic. Also, all the additional information (like your email or website) can be published, if you wish.
Thank you once again for your wonderful work!
Kaerdu.

That's fine, as long as you link back to the original in author notes. That's actually more for your protection - there have been incidents in the past where someone thought the translator was trying to "steal" the story and pass it off as their own. (You would not believe how many people were embarassed because they jumped to conclusions.) A note saying you have permission and linking back to the original version avoids that.

Thank you for permission.
