Administering Your Translations

Whether you want to internationalize a Facebook Connect website, an FBML application, an IFrame-based application, or something else, Facebook Translations allows you to have complete control over every aspect of the translation process. To make the process as simple as possible, we've divided the administrative tools into two main categories.

1. High-level administration. These settings allow you to manage your application at the granularity of an entire language. You can choose to enable or disable the translatability of your application, enable or disable the availability of any existing translations, see progress, and give specific individuals the ability to manage the translation of your application for you.
2. Low-level administration. These tools allow you to search for and examine specific pieces of text and their respective translations. (Coming Soon!)
