This task should be easy if you've worked with Wordpress with Buddypress plugin. I have a Wordpress/buddypress theme and trying to translate it. The theme has translation file (.po file) but when i translate it and upload to server, i can see only few translated strings (mostly WP strings) while BP strings are almost all in Engish still. When i compare the theme's translation file with Buddypress official translation file, i notice that the theme's file is missing a lot of strings from the buddypress.
Task: i will give you the theme and you should install it to your WP demo site and localize it to any language available. If the theme's translation file is missing strings, you should add that from buddypress translation file and send that to me. In other words, make the theme 100% in your native language. I will use that translation file then.
