In this era of globalization, language should not be a barrier to sharing information. Keeping that thought in mind, Liferay has always been very powerful in terms of its localization support. The latest version of Liferay supports 33 languages out of the box. Most of these translations are done by either the community, or sponsored by customers. Liferay also supports changing interface from one language to another on the fly, using Language Portlet. Liferay also provides a very nice interface, through which you perform translation of Liferay in your language. You can access that interface using http://translate.liferay.com.
