Hi diestreve319, unfortunately the story that you already published wouldn't be eligible for Writers Camp. Per our rules:
The story you submit must not have been published previously on Tapas or elsewhere, either as a novel or a comic. In other words, your story should be an entirely new work, previously unpublished in any form or medium.
We hope you'll still consider entering with another idea--and even if you decide not to, we're excited for you to be a part of our awesome community of writers!
