Google Docs has rolled out a major feature — you can now translate documents into 42 different languages, right inside Google Docs. That means no copy-paste into Google translate anymore.
To translate a document, just go to Tools » Translate Documents and choose the language of your choice. Google automatically detects the language the current document is written in.
Although translate technologies on the 'net are not reliable, this feature is a good one. This integration will certainly help people collaborate with non-english speaking world.
