I think I have too many subreddits that I'm subscribed to for this to work! Won't let me create a multiteddit, might have to manually create a few and do it bit by bit. Supposedly I'm subscribed to 613 subreddits and it will only ever pull 250 at a given time... This is probably a good opportunity to start fresh and only subscribe to the important stuff (although many probably won't have communities here yet anyway).
Does anyone know if Lemmy also has a limit on how many community subscriptions it can present?
