Hi Sam! thanks for your answer;

A my-languages directory would probably be the way to go.

Well, then bb-config.php needs to have last lines changed ;

// Change this to localize bbPress.  A corresponding MO file for the

// chosen language must be installed to bb-includes/languages.

// For example, install de.mo to bb-includes/languages and set BB_LANG to 'de'

// to enable German language support.

define('BB_LANG', '');

I tried a my-languages and a bb-languages folder but no way.

Can you link to the language files you were trying to use?

I had an old .mo file stored in my hard drive. I think it was for bbpress 0.7 or a previous version, not sure.
