The folks at Google have created a Website Translator Gadget, enabling you to translate your website into 50 languages. It is easy to use; you just add a few lines of code to your website. Then, when users visit your website, they can select the language from a drop box, and Google will translate. Or, if the user’s browser language setting is different from your website language, they will be prompted to translate into their own language.
This is the coolest and most useful website add-on I’ve seen in quite a while. Enjoy!
