When you write or edit a story, you can decide how to share it using the Publish box in the upper right corner. The Visibility control lets you share stories with the entire community (Public, the default), but by clicking Edit, you can also choose to password protect it (and give the password—for now—to to those other beta testers you select) or keep it private. You can also click Publish Anonymously to remove your byline from the story.
Comments don’t appear automatically on the site. We leave it to you, the story author, to moderate them. This helps us exclude spam, trolling, and abusive material, as specified in our Community Guidelines.
When someone comments on one of your stories, you will (with rare exceptions) receive a moderation email. It will quote the comment and offer links to:
Clicking any of these links will take take you to the Comment Moderation page.
Alternatively, when you sign into Retrospect, you’ll see a comment icon and a number in the top right corner, next to your name. 
If the number is more than zero, you have comments waiting. Click the icon to go to the Comment Moderation page.
The choice is yours, but please moderate comments promptly.
You can also turn off comments entirely for any story you choose. On the Add or Edit Story page, scroll down to the Discussion section and uncheck Allow Comments.
Occasionally, you might start a story in response to a particular prompt, but it actually turns out to be about something else. You can change the prompt assigned to a story on the Add or Edit Story page. Scroll down to the Assigned Prompt field, pull down the menu, and choose a new prompt. Or choose My Own Topic if there’s no prompt (yet) that fits your story.
You can also suggest new prompts using the Contact link in the lower right corner of any page. Choose Story Prompt Idea from the Topic menu.
It’s actually quite simple! Click Share on its YouTube page and copy and paste its web address (URL) onto its own line in the text box on the Add Story page. It will look something like this:
