BuddyPress.org

We changed them on our site. Basically you go into the plugins/buddypress/bp-languages folder and get the BuddyPress.mo file. Then use a program called Poedit (you can search the web for this), and use it open the BuddyPress.mo file. You can then change the language in that program. When you save the file with a name, say TEMP and it will also save a TEMP.po file. Put that back into the bp-languages folder. Then add a new bp-custom.php file into your plugins folder and put this code in it:

define( ‘BPLANG’, ‘TEMP’ );

if ( file_exists( BP_PLUGIN_DIR . ‘/bp-languages/buddypress-‘ . BPLANG . ‘.mo’ ) ) {

load_textdomain( ‘buddypress’, BP_PLUGIN_DIR . ‘/bp-languages/buddypress-‘ . BPLANG . ‘.mo’ );

}

Change the name TEMP in the above code to whatever you called the po file.

That should do it.
