Your plugin looks amazing, but what happens if the plugin I want to translate haven't got any .MO file (only .php .js ...) ?
Like this one: http://wordpress.org/extend/plugins/social/ Lots of php files there... but it has lines like:
<p class="nopassword"><?php _e('This post is password protected. Enter the password to view any comments.', 'social'); ?></p>
That's the chain 'social'... but no .MO or .PO files!??
Thanks for your time!
