Cluj should be enough instead of Cluj Napoca, Lvov for Lviv, Joburg for Johannesburg (even official website is http://www.joburg.org.za/)
Also some countries aren't spelled out in the results.
I don't know, if that is possible :)
Also, a small error on this quiz: Shetland would been Lerwick, though that doesn't have more than 10.000 inhabitants.
This quiz really deserves to have points, the work going into it and the quiz itself is great.
