What fanfiction resources do you know about?

[JaxRhapsody]

Looking to compile a list of fanfic resources beyond the usual AO3 and FanFiction.net. What sites, forums, tools, or communities do you use or recommend? A few I know:

• FanFiction net, Archive of Our Own.
• Questionable Questing, Sufficient Velocity, Space Battles forums.
• Webnovel, ScribbleHub, Wattpad, Royal Road.
• fichub.net, ficdb.net, HPFanfiction Recommender (https://hpffrec.hackesta.org).
• Dark Lord Potter forum for dark Harry Potter fics (also has sections for other fandoms and off‑topic).
• Goodreads, StoryGraph (not great for fics). I use Calibre to track reads + FanFicFare to get EPUBs.
• Various fanfic subreddits and lots of Discord servers (r/DarkFics, The Dark Wolf Shiro server for gamer fics). I wish I knew a discord for dark fics.
• Lemmy instance https://literature.cafe. Would love a Lemmy instance for fanfic specifically. and I would like to know which NodeBB communities there are for fanfic specifically or literature in general.
• My reading list.

Anything of relevance I missed?
