Hi wonderwoman (great name!),
Welcome to the Systems Change Alliance Community.
Apologies for my slow reply - somehow I missed your questions here.
Your piece should be flash fiction - a short short story. We don’t need a synopsis.
You don’t need to include all the principles of what we stand for, more that one or more of them should be an inspiration for how your story unfolds.
There is no specific genre, other than flash fiction. I will post a link to an article on this genre in the following reply.
There is not age limit and no entry fee.
The time and place of your story is up to you.
I hope that covers everything. Feel free to ask more questions if you have any.
