This facility looks like it could be of great use to translators. You can add collaborators and thus, if you trust the client, you can have a constant feed-back system. On the client side, it could ensure some amount of security against delay or default. At any given time, the client has access to the work.
How does one go about this? You add collaborators. So it can be your client and you or your team and you.
Ease of use: it is almost identical with the word doc format. You can download it too. Also it saves the need to open a word doc on your PC (assuming, for example, you were forced to work for a time on some public or other PC. It would, of course, be foolish not to download it regularly as the version on your PC is your proof, so to speak.
For the moment a fellow translator and I are using it more creatively as we both love writing short stories- we get to edit each other’s work.
