I'd like to change some of the default WP text that not defined in the templates.
An example is the option that says "ERROR: Enter a username or e-mail address." which is defined in /wp-login.php line 65, but this could essentially be any line in the PHP.
It's not a problem if you use translations, but what if you want to change it in English? I can't find an English translation, as I guess that's the easiest... don't like the aspect of filtering 'the_content' every script call... any ideas anyone?
