Follow the link to Tangle's prompt, which is available to anyone who wants to use it. You can't get into the hard core of write club, but you can write a story to fit the prompt and you can even join The Writers' Block to run it through our queue in the fiction-workshop and get help making it the best story possible.
We also help with brainstorming, if needed.
Also, the top link in this post goes to the post that describes how to participate. Good luck, @juliusjamex!
