If you would like to translate a text or an entire site from one language to another you should try . I tried it on a few sites and it's not the best result but quite understandable.
There is also a dictionary from-to several languages and a little gadget which you can add to your webpage. We have added it to Wohill as well as you can see to the bottom left (at least for some time).
Add this script code to get the gadget:
You can make some personal adjustments by changing the querystring in the url:
| up_source_language=en&w=160&h=60&title=&border=&output=js |
The gadget on Wohill looks like this (in swedish):

When you choose to translate a site, either via Google Translator or via the gadget, your site will appear with a different address and a different language but otherwise look (almost) the same. This is how Wohill looks in german:

When you move the mouse over any text a popup window appears (as in the picture above) which shows the original text and a possibility to contribute to a better translation if the one provided was poor.
