This is my first new thread since joining so I hope this is in the right place and isn't a question answered elsewhere. I understand that if you write a short story, and post it on a forum it will be considered published and wont be taken up by elsewhere. But lets say I post a short story of 1000 words, but then expand it to some 4000 words without posting that version. Is it still considered a published work, or does the fact I have built on it make it a new piece of work and therefore unpublished? Does that make sense?
