I've heard a friend make a suggestion about this year's contests, I won't say who they are, they can post here if they want, but I do agree with the complaint, so I'll reproduce it here.
It's a bit weird for people to be able to choose any of the prompts in any month (as long as they don't repeat a particular prompt). Because, for instance, I might choose the prompt that suggests superheroine transformations, while Jay might choose the one about size change.
We're competing with different themes in a given month. The old style where everyone had to stick to the same theme for a month was both more intuitive and fairer.
