Please, look at articles such as:
http://en.wikipedia.org/wiki/Macedonians ,
http://en.wikipedia.org/wiki/Macedonian_Slavs ,
http://en.wikipedia.org/wiki/Macedonian_denar and similar.
Greek nationalists, supported by one Bulgarian nationalist (just to
say that Bulgarian Wikipedian community is not nationalist) are
forcing naming (modern) Macedonians as "Macedonian Slavs".
Even (some) people on English Wikipedia think that they can vote about
the name of one ethicity/nation. This is a horror. I urge to all of
you to stop that (Greek) nationalist orgy there!
Wikipedia is not the place for nationalist propaganda.
