I played the senior tennis tour in europe during russian times, and still have many friends there and still send xmas cards etc, people in Poznan, Kielce, etc, and I have never had a zip code for them, some countries do and some don’t, for example Thailand does, but their codes also fit cities in the usa, where Cambodia does not! My friends for Poznan during russian times took me to Krakow sight seeing, and they had just opened this new restaurant that day, and it was the first Pizza restaurant in Poland, it was small and nothing like an american pizza but good, especially then because there was not much food, had to stand in line for bread and for gasoline, uggah gasoline lines sometimes for several days, but the people were great and seemed to love americans, maybe because my grand mother and grandfater were both born there huh?

In Polish cities every street has a different post code. I also tried to set Yahoo! msn to show the weather forecast in Lublin, Poland (where I live) but it seems it only works for the United States. The previous version of the Messenger has other options and I could see my town’s weather in it. The new one won’t do that.
Now I use the msnbc weather service - here’s a link to the Cracow’s forecast:

30-067 is the “zip code” for Krakow. I’m not sure if it will work for the US weather site.
