How to build a JrElastic multilingual-based site using the Site Builder?
Using Jamroom
The language files and the jrCore_lang function are what makes the site multi lingual.

You'll want to make sure that whatever you want translated is using the jrCore_lang function.
ie.
{jrCore_lang skin=jrCore_active_skin id="XX" default="Default Text"}
where XX is the language id you want and the Default Text is whats used if the function doesn't find the id in the language file.
