Please change the first sentence on the polish version of your web page. The polish word for “free” can be of course “wolny” (it is one of the meanings). But “wolny” does not mean “free of charge” but independent or also slow (!) – you do not want Linux to be called slow OS. You need to use the word “bezpłatny”. Such a mistake in the first sentence frightens away every possible user trying to find some help on that web page.
