It occurred to me when I was posting a reply to Carlo that most of you have likely been using Google Translate. I found a translator that does a "back translate" so you can see what you think you said actually looks like to the reader. You'll be surprised how much you need to rework your original text to get the context right in the target language. it's IM Translate and available as a free download.
