You Should NOT: Translate into one language and then back to the original language FROM the translated language.
Example:
Don't translate from English to Spanish and then translate the Spanish version back to English. You'll get a hilarious result as did Brian Lusk mentioned in the 9/28/2007 Southwest blog.
NOW THAT'S TRULY NUTTY, Southwest!!! LOL.
You should not first translate a page into a foreign language, then take that translation and translate it back to English.
You end up getting mumble jumble!
