Welcome to The Raven, tokamil.
Don't worry about your English. It's fine and better than some of the native speakers on here!
One of my mother's best friends is married to a Pole (last name: Dziewirz - pronounced "Jevish" in English) and he is a very funny guy. Our families are great friends together. I've never been to Poland but my girlfriend went to Warsaw a couple of years ago.
Some of the coolest posters for "Raiders" are the Polish ones! Strange, different & very colourful.
