I am Greek and Macedonian.
Living in the city of Thessaloniki (the name is from the sister of Alexander) and half an hour from Pella- Vergina, the palace where Alexandros and his fatehr Philippos reign.
Alexander (Alexandros) the Great was both a Greek and a Macedonian. He considered himself Greek, spoke Greek, was in love with Greek culture, and spread it across the world. He simultaneously considered himself Macedonian, however. He was most definitely not Slavic. Macedonians were a people living to the immediate north of Classical Greece in the area now mostly contained in the modern area known as Greek Macedonia (of which the capitol is Thessaloniki). Ancient Macedonians spoke a northern variety of Greek, as well as Koine Greek once it spread across the world. The modern nation of Slavic Macedonia contains very little of Ancient Macedonia's territory, and actually mostly coincides with an ancient nation called Paeonia. Slavs didn't actually appear in the Balkans until almost a thousand years after.
So I cannot understand the language you are writing in this "Macedonian" section.

FYROM is the name until they will find something else or spread to the nations where people are from (Serbs, Bulgarians, Albanians, Greeks).
