This website uses an automated Google Translation system.
(it can also be known as Machine, Computer or Automatic Translation).
The website is written in English and is then translated into Thai (and many other languages too) on demand. Because the text is translated by computer - without human intervention - sometimes the translated text will look quite odd.
If you are interested in this service, please visit the Google Translation Service at http://translate.google.com/#. When you copy some text to translate - say from English to Thai - Google offers you the opportunity to help improve the transation.
