When using eLUNa, bear in mind the following information:
Expiration date: Once a document is uploaded in eLUNa, it has an expiration date. If no change is made to the document, it expires after 7 days, which means you cannot work on it any more, but it is still possible to download your translation for 2 more days. After that the file is deleted forever. If you stop working one a downloaded document for some time, to prevent its deletions, just go in the file once or twice a week, modify something (adding a comma for example, that you can remove later) and click on Apply. By applying a new segment, the expiration date is reset for 7 new days.
