I have no experience with Polish; I’ve never been to Poland, and never met anyone from there either, now that I think about it.
But as niski pointed out a month ago, adresownik works, even if there is no English translation available.
That’s okay. I have Google Translate. 😐
It’s simple, and maybe a little confusing if you’re like me and aren’t sure what it’s asking for.
And as niski said, other than name, family name and e-mail address, it doesn’t seem to hold much.
But it’s there and it works. 😉
