When you write a comment, like this one, that only makes sense in the context of another—in this case your earlier question—you should make your later comment a reply to your earlier one.
More generally, you’ve posted these questions, all within a few minutes of one another:
How do I post a fanfic?
Is there a guide on how to write rationalist fanfiction?
These really don’t need to be separate comments. Better would have been a single comment in the open thread saying something like “I am interested in writing rationalist fanfiction. Has anyone written a guide to doing this? Where should I post it—on fanfiction.net, AO3, or here, or somewhere else? If I want to put it on my own website, how do I get one?”.

Am I meant to post my fanfic on fanfiction.net or AO3?
Or should I create a new article for it?
How do I get my own website?
