I haven’t mentioned my fanfiction here before, but I’ve been very active on AO3 the past few years. My biggest project is a 222k Harry Potter series, starting with Harry Potter and the Problem of Potions. It taught me a lot about writing long pieces, even more than some of my novel drafts, and I recently finished the sequel, Harry Potter and the Language of Serpents, which is entirely Cursed Child fix-it fic set after Hogwarts and I have no regrets.
