No, because in English we use the plural, and in French or anothers languages we can the singular. I think the best idea is to have a specific string for this message because otherwise it is confusing.
I know it’s not one of the most important things. But this is for the evolution of UsersWP, and that’s the reason why i take time to explain this.
Actually, thats the strings used in the translation files (pot / po / mo) for: en_EN => fr_FR
No %s found => Aucun %s trouvé.
Posts => Articles
Comments => Commentaires
Personally, if I was sure that these strings were used only on this profile page, I would customize. But I doubt that a generic term like “Comments” or “Posts” is not used elsewhere, and therefore I prefer to respect the exact translation of these terms.
Anyway, I need to know if you are going to correct this, or if I need to write down these customizations to avoid losing them during the next UsersWP update.
