I've translated the string "Account confirmation is required. Please, check your email for the confirmation link. To resend the confirmation email please click here." in app/locale/it_IT Mage_Customer.csv
"Account confirmation is required. Please, check your e-mail for confirmation link. To resend confirmation email please <a href=""%s"">click here</a>.","Conferma account richiesto. Per favore, controlla la tua e-mail per il link di conferma.. Per rinviare l\'email di conferma <a href=""%s"">clicca qui</a>."
But I still get it in english... As far as I see it's the only string that I don't get translated in italian, why is that?
