Some other writers/readers and I have taken it upon ourselves to create a safe place for people to post their stories with the minimized threat of plagiarism. With the help of Plagiarism Haven, we've created The Write Away, a private Livejournal community where members can post their stories and help others improve. At the moment, membership is closed to everyone but those who are a member of the Plagiarism Haven community. This may change in the future, so keep a weathered eye out.
We encourage everyone to join both communities and come join the fun.
See you there!
