PSA: You should know that Settings > Migrate Subreddits exists. All you do is login to your old Reddit account, copy a “multireddit” link, paste it in Voyager and you’ll be able to search the fediverse for those topics/communities to subscribe to.
You may find communities that are missing here if you’d like to run/manage your very own community on a topic you enjoy.
Hope this helps. I just found this feature today and subscribed to a bunch of communities.
Just a reminder, If you get an error while trying to search communities with this feature, you may have hit the rate limit of the server.
I was using lemmy.world to find instances for my own instance and almost every other search gave me an error. Waiting about a minute was enough.
Interesting, that’s likely to have happened to me and I didn’t realize it. Thank you!
