[Mailman-i18n] Question about translation of PO file

Hi there I know I should ask this question from Mahyar Moghimi, and I have already asked him, but since he is on new year's holidays and can't reply soon , I ask it here. I tried to translate a part of mailman.po Into Farsi language. I attached the translated part here as a text file. I only translated short and important phrases now, not long ones. Now I have 2 questions: 1- Am I writing the translations in the right positions? 2- How can I test to see if the translations are working rightly? I have already read the How-to-translate guide, but I got confused because there were lots of various guides and some of them where not clear enough. Best Regards
