Hi all... long story short: My father had a roommate in his student days from Guinea-Bissau that he was friends with, but broke contact during the years. My father is from northern Serbia and he was in the city of Zrenjanin when there was a decent number of Africans studying in Yugoslavia through the non-aligned movement. I would very much like to find a contact with him for my father and I do not know how to proceed. Reddit is my hope. I know his name and surname (the guinea-Bissauan roommate's I mean). Could anyone point me to a site, forum, or anything similar where I could look for Guinea-Bissauans who studied in Yugoslavia or something?
