Foresight is only translated as well as the applications included, which in the GNOME world isn’t really that bad. But there is always room for improvement and Foresight maintains quite a few things that haven’t been translated yet, website, wiki, etc.
I am very pleased to see some community members looking to get involved in localization. We now have volunteers for German and Portuguese, as well as a volunteer to organize the initiative.
There is also now an IRC channel on freenode dedication to the translation team, #foresight_i18n
