Your are right, Ruth. All the translation are done online. You don't need to download translation files, purchase translation tools, or upload the finished translation. It saves a lot for translators and achieves the collaborative translation in the real meaning.

You may refer to http://www.translia.com/node/115107 for more detail about how to start translation online.

Any question or comment, feel free to let me know pls.
