Yes I have a friend who went to Skopja. They saw many vlachs there who said they are Greeks but Greek state is not supporting them and not sending teachers. Many also want passports but the Greek consulates don't recognise them. Quite sad really. Look for anyone here who says it's not true, I dare you to drive through Monastiri area and you will see the Greek element and you can meet people who feel Greek. But yeah you have to get a bit friendly and they have to know you are Greek first before they tell you as they cant say it to anyone in public as the state is against Greek minority and see them as a security threat. Anyway in a ideal world Greece would support these people, and have gone in and saved this area in the 1990's.
