Hello,
I'm ManuelGR, an administrator from es.wikipedia. You can find in attachment our updated translation for LanguageEs.php.
I don't know which is the procedure for sending this updates, I beg your pardon if I shouldn't bother you with these issues. In such case, please tell me how can we update the translation. Thanks.
I edited the revision 1.21, which still has the HEAD tag at the time of writing. I respected the UTF-8 encoding and hope it will not be broken while sending it.
Thanks for your attention. -- ManuelGR from es.wikipedia.org
