This was a neat article I stumbled across on plotting short fiction: http://twowritingteachers.wordpress.com/2011/04/13/plotting-short-fiction/
The author shows a helpful chart that she uses to help map her stories. Specifically, she discusses how to work out scenarios. What I really liked what how she emphasizes the idea that "plot happens." The best scenes are created when you just let the characters react to each other or the scenario.
I thought it might be a useful resource if anyone happens to be stuck on their story. Maybe to help work through the writer's block...?
