I started translating into Polish. Unfortunately, I can't do it as fast as Dr. Mary Calaveris (respect). The Polish language (like the others) is contextual. Many words and sentences have different uses
in specific situations. So after the release of osCommerce v4, the translation will certainly need to be refined based on the facts. I attach files with the current progress of work for possible verification. I need comments and highlighted lines in the (.ods) file for my own use and verification after osCommerce v4 is released. I will try to finish the translation by the end of January 2022.
