Help for italian language translation ...

[according]

Hi All,
I try to translate in italian language all the sections of website (http://www.according.it).

It's not easy... a part of the site has been translated but I can not find many words or phrases to be translated in php pages.

Example. In home page there is the words "Read more" I need to change as "Leggi ancora" or in each post (example http://www.according.it/?p=15) there is "dicembre 22, 2008 by" I need to change "22 Dicembre 2008 scritto da" as in topnavbar where I change the js function... but I do not find pages ...

I must search for any word or phrase or there is a more rational method?

Thanks!

Otello
