Sometimes a translation (typically your own) is not reviewed by anyone else for a fairly long time. This is unfortunate, but there is no reason to keep it in draft state forever. If nobody reviewed it for a substantially long period (like 3 or 4 months), commit it as it is. Readers may report bugs as well (and they do!).
It is important to record somehow that this published translation still lacks appropriate review. If the suggestion in the previous section is implemented, it would mean leaving the relevant task ‘Open’ and ‘Ready For Test’ despite the translation being officially online. You may also add a comment to the PO file.
