Sorry it took a while to get back to you - I had to check the status of the Delphin's contents plan from that team.
1) Actually you were not a validator of that project (it's separate from the wpcom project). I've promoted you now, so you should be able to import translations.
2) The Delphin team said there will be a major change in the contents of get.blog site in late November. It's probably the best if you work on the translation after then, so that your effort is not lost.
Thanks for your help! Let us know you have most of the project translated after the content refresh next moth, then we can deploy get.blog/sq in the future.
