In any case you can use Transifex to translate the po online or upload a new version of the string. But I reccomend to wait until I update the POT files at transifex once everything is merged and updated in the main git repository. From now we just are testing how does it works, and works very well!

I plan to release the first candidate during end of next week so that will be the announce of translation submissions.

pls be informed that tx will not preserve the header of po file. that means the previous translators' info will be replaced by new commit.
