In fact an english translation has already been submitted and is waiting for evaluation (you should see it now as you are expert ). If the translation is rejected you can submit your own, otherwise, the translation is accepted and closed.
I still don't quite understand how the rejecting and evaluating process works. Why is it that when I reject a translation, 1) I have to evaluate it, and 2) I get sent to a page to edit it, even if the source language is not one of the ones I know?
