Hi.
There is now a Polish translation file available for download: http://www.mairlist.com/download.php Thanks to Michał Ulman, who created this translation.
I have set up a dummy page in the Wiki where I will explain how to create translation files for different languages with the free poEdit tool. Perhaps there are some volunteering native speakers out there who would like to make mAirList available to their fellow speakers.
