Community dedicated to the world of Harry Potter.
Mostly focused on books and fan creations, movie content is accepted but should not overwhelm the community.
I have no skin in this game, but wouldn't it make more sense if you have one community for your "ships", and then if it gets too busy / crowded you splinter it off?
I say this because creating 3 communities for the same thing (fanfic) but a different flavor (the 'ship) might make it seem like empty communities. Unless you plan to populate all communities with content all the time.
I guess, I was just mostly basing these communities off of their respective subreddits.
Yeah that makes sense. Lemmy doesn't have the same amount of active users though, so it might be very slow at the start ;) Good luck!
Thank you
