I don't know how you could miss this thing:
The page title of the admin-header.php and in certain pages as post.php and edit.php there's no __( string ) in those strings...
I have some people I'm helping setting up wordpress as their CMS and they just don't get the POST name what is for. So, doing some tweaking I set up a function to translate just those words for something more meaningful to them, like NEWS. It does right on the left menu, on the body, but the titles remain the same because those haven't the __( ) function in them.
You should add it so in cases like this people don't have to edit the core files in the wp-admin.
thank you people.. cheers.
