Hello,

the main language spoken on this forum is German at the moment, so I'm not sure why you'd want to add a Polish version. It is also already possible to change the language of the forum software to English in the footer. I think it shouldn't be a big problem for the team to integrate a Polish localization for the forum software, though. I think you could also contact warpspeed directly, since he's usually quite busy and might not see your thread.

Hope I could help!
