Hi Wojciech I'm very happy to hear that! We currently do not have any Polish translation for X2Go Client yet. Any help is very much appreciated. For a quick overview of how translating is done, please read http://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=README.i18n;hb=HEAD Due to my latest changes with a lot of updated messages, I will need to regenerate all translation files and ask translators to go re-translate all new and changed messages. Note that X2Go Client is primarily developed in English, so contrary to what the linked document says and how this procedure was handled in the past, I would like to base old and new translations on the English original, instead of the German translation. If, however, your knowledge of the German language is better than your knowledge of the English language, you can also start with the former. In any case, I will take the necessary steps soon and provide you with a new translation skeleton. Stay tuned. Mihai
