That is a good question. Here’s what I know:
To Review text with Transifex, you need to be appointed as a Reviewer (or higher rank).
Reviewed text is supposed to be protected from changes, except by other Reviewers.
As yet, we have not appointed many Reviewers to the task. It is a little hard to judge who would be suited to the task. This is an issue we’re trying to work out.
Our Transifex feature is still a WIP, so I have no ETA on when the translated pages will be made available.
There are a few other minor hiccups that need to be sorted out before we get that far.
Rather than bog this thread down with further discussion of this, I’ll make a new one sometime soon. SpongeDocs needs a pow-wow to get some wrinkles smoothed out, and maybe get the translation teams to pick some good Reviewers.
