The Polish translation contains a pl_PL.php file, which comprises a function that does month name declension. It seems such .php files aren’t used on WordPress.com, which seems reasonable from a security standpoint, but it results in month names being improperly displayed on Polish WordPress.com blogs. Is it possible to implement a system that would allow such functions after, e.g., reviewal from a WordPress.com staffer? You can see the entire file here: http://i18n.svn.wordpress.org/pl_PL/tags/3.2.1/dist/wp-content/languages/pl_PL.php.
P.S.: A “com” tag would be nice.
