Language in the forums

Hello, I am trying to add topics in my forum (my site) and I have a multi language installed, french and english, is it possible to separate the forum subjects so they can only be seen in their proper language ??

it is possible but it needs coding based on languageID or detection the content language.

adding field in forum table and form. And in php script check what they wanna see...

example: show only Fr forum posts, show only En forum posts, show all

I did this for the news module and it works fine.

Sounds easy enough when you know what you are doing lollll not my case ;(

well it needs some work but if you know where to look and place the php code you can do it.
But it depends how you wanna build it up.

for my news mod i have a language field in the table that holds the EN or NL and in the php code i check what the members have entered as language and use a 'EN' or 'NL' filter in the news news blocks and search/view pages.
