...to a few questions asked under the last post.
1) You may write a story that is a prequel, sequel or companion piece to a pre-existing story or stories. The new story must of course meet the minimum word requirement and the story/stories it relates to must also be available for reading online via a link.
2) Co-authored stories are acceptable.
3) You are welcome to complete a WIP to meet the challenge as long it has not been previously posted/printed/archived anywhere public.
