How to send notification mail in users language ?

Hi

i'm just discovering PP from yesterday :) and i'm not english, then i'm using other language, but all the noficiation mails are sent in engleish.

is there a way to be able to send the mail in the prefered users language ?

i ask it because users on my PP are not from the same country, we speak in english but we'd like to have the notification mail in our language like it is for the GUI.

Thanks for your help :)

Cheers.

Cali.
