In order to create a Multilingual Site, you have to use a translation plugin. Multilingual plugins offer WordPress users the ability to run a multilingual site with a single WP install.
The multilingual WP plugins are free and premium (paid). The most popular premium plugin is WPML.
WPML ( Tested with all VamTam themes)
WPML is a premium multilingual plugin, designed to make it easy to build and run multilingual sites and blogs, and translate pages, posts, and other content. The default install offers more than 40 languages, and users can arrange different language content in the same domain via language directories, in sub-domains, or in completely different domains.
One of the other cool features of WPML is the ability to translate comments, so when international visitors comment in languages you don’t speak, you can read them and reply. As a premium plugin, the cost runs between $29 for blogs and $79 for websites.
