I entered a short story competition. Surprise, suprise, I did not win. I was not on the shortlist. And I was not on the very, very long list. It could be that my story was rubbish. But I am wondering if another factor may have come into the equation. I used a vehicle trade name in the title and also mentioned it in the body of the piece. Can anybody tell me, before I delete this story, would mentioning a specific product render me and my work null and void?
