I have access to transfix for CB Privacy but unless I have not understood how to do it, I cannot propose a modification for a text.
When a member de-activates its account, he receives a confirmation email with subject :"....... Confirmer la suppression du compte". Contents of the mail is correct with "Veuillez confirmer la désactivation du compte en cliquant sur le lien suivant " but mail subject is misleading as it should be "Confirmer la désactivation du compte"
I think this is text 150 "Confirm Account Disable" "Confirmer la suppression du compte" in transifex that should be replaced by "Confirmer la désactivation du compte"
