Hi, tell please, how can I create an oxwal based multilangual site?

I need localise my site for 3 -4 languages (Russian, English and etc. ).

Is this possible and if yes, how can I do this?

Now it is possible.
You are able to create new langs in Admin Panel->Settings->Language.
After you will have more one active language on your site, your members will see language dropbox on the site's header. And they will be able to switch languages.
