The rules for the anthology are simple: comment to sign up and be assigned a letter. You will be committing yourself to write at least 100 words of gen fic by October 23rd. The only requirements are a minimum word count of 100, touching upon the Quantum Mirror somehow in your story, and keeping your fic gen (yes, even if you're writing an alternate universe; gen ficathons are too few and far between).
