A word of warning: Chances are that in addition to not paying, R'osity acquired reprint control over the article, so it can't be published elsewhere (as someone seemed to suggest above). Don't know how common that knowledge is. Just because they didn't pay you doesn't mean they don't own it. This is why I never enter those "entries become the property of the contest mogul" contests. They are essentially scams to gather up stock photos, etc. Picture it: A short story contest where the entries become the property of the mag. Everyone sends their best work, and the mag now has a pile of 10-100 stories it can publish without having to pay for them.
