Forum:Change default language

I'm an admin at basilicus.wikia.com. Another user at Basilicus decided to start a translation project into Spanish, but made the new wiki at spanishbasilicus.wikia.com instead of es.basilicus.wikia.com. I know that you can request a url change, but will changing the url into es. change the default language interface into Spanish? Currently, the default language in the Spanish wiki is English, which sort of defeats the purpose. --Article editor 18:53, May 7, 2012 (UTC)
