I added a web page translator plug-in to this site. It has the ability to translate your web page to thirteen different languages. Pretty cool, huh!
It is called Global Translator by N2H.
You have the option to use either the Babel Fish or the Google Translation Engine. It comes with a built-in cache system in order to reduce the connection to the translation engine every time a page is loaded.
The permalinks in the translated web pages are search engine optimized by adding the language code to the beginning of all your URI.
