That doesn't suprise me at all. There's a lot of polish disgraphs and diacritics in those names and you probably have no idea how to pronounce them and I understand that. I lived in England for few years and I was always trying to get my mates to say some harder words and they struggled a lot. The ones you mentioned are real tongue twisters, so it seams that taking control of Unia Wapno was a really wise choice
Names of people are a bit easier because there's no Polish diacritics used for people's names in FM (for example Lukasz instead of Łukasz, Rafal instead of Rafał etc.).
Anyways, as a Polishman I'll be following the thread to see how you're getting on. There's a long way up to the top flight and it will become more difficult as you reach III Liga (4th tier) for sure. Good luck mate!
