How can I filter the displayed posts by language?

[bodzio]

My international guests use at different languages.
I have multilingual web site. I want to allow to choice by see all entries or only those in your selected language (English or German).
Phoca data base has already field "Language" - but just how can I use it?

Hi, this is the same like in Joomla! Every item can have own language and if e.g. the post is in german language, then it is displayed only on german subsite.
