Thank you, but a lot of French people in fandom write in English far better than I an do. (It's almost mandatory, except in a few fandoms, to be read ^^)
I try to write fics in English, and each time I find a betareader, I cringe when I'm shown how many mistakes I make.

(And sometimes, I hope that when my fics have no feedback on the Les Misérables kink meme, it's for the grammar and not for the content ^^)
