I'm trying to post a fic in the fic thread, but its giving me an error that it hasn't been created. Is there a trick to it?

Posting fics here is very complicated... and I suspect I've forgotten half the steps. You have to upload the fic to the fic library, and then it creates a file in that section. And yep, I've forgotten all of the steps to upload a fic. I guess you could start by clicking on the 'Fic Library' button at the top of the page!
