Ok, thank you.
I will do it by myself.
But I have some issues with my translations...
First, what I translate in the "Startup.pot" file doesn't change my homepage (ex : "Logout" stay as "Logout" instead of "Deconnexion")
And, for the "Last Article" section, I have search in all the template file to put "Lire plus" instead of "Read more" but "Read more" stays on the homepage, it makes me crazy I can't find why is it like that.
Thanks for you help in advance,
