Have a question about how the TVTropes wiki works? No one knows this community better than the people in it, so ask away! Ask the Tropers is the page you come to when you have a question burning in your brain and the support pages didn't help.
It's not for everything, though. For a list of all the resources for your questions, click here. You can also go to this Directory thread

How to Create a Work Page has the basics for you.
I recommend editing Sandbox.Expect The Unexpected instead of a real page and ask later if it's good enough for publishing.
TroperWall / WikiMagic CleanupSee How to Create a Work Page for detailed information. You can indeed create a works page for a fanfic whether you’re the author or not. It’s a good idea to draw it up as a sandbox page first. Once you have it reasonably close to done, feel free to ask someone to take a look at the sandbox page and offer criticism.
The only types of pages you can’t create are YMMV and Trivia pages allied with the works page. You also can’t provide a review of your own fanfic. Otherwise, you should be good to go.
EDIT: Looks like Amonimus beat me to it.
Edited by BoltDMCClarification: You can edit the Trivia subpages for your work, but anything you add there has to be independently verifiable outside of your edits. "I know this because I'm the author" isn't allowed, but "Word of God: The author's note on chapter X says Y" is fine.
Suddenly I'm... still rotating Fallen London in my mind even though I've stopped actively playing it.

Hi! Was just approved this morning. I use to be on this site years ago but I have no clue how things really work behind the scenes so I need a little guidance. I'm the co-writer of the most popular Five Nights at Freddy's fanfiction on fanfiction.net (not including rated M stories. We're second place in follows and favorites behind one rated M fic.) Several of our readers have said we really need to have a trope page but I don't really know where to start or how to add tropes or even if I'm allowed as one of the authors. Here's our story. I've been writing 50% of the story for the last seven years since Chapter 12 and there are 179 at the moment with more planned. I just don't get credited each chapter, which is fine, because I'm just so involved it gets tedious. Arctic Vulpix is the publishing writer. https://www.fanfiction.net/s/11737586/1/Expect-the-Unexpected
