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.
Does this give Lemmy or WefWef (Voyager) your Reddit credentials?
No, it just takes a multi Reddit link that you paste, and for each subreddit, it will search for alternatives across the Fediverse.
You can select them one-by-one and subscribe to any you fancy.
No it’s just a string of text: “https://old.reddit.com/r/subreddit1+subreddit2+subreddit3”
Nope. The multireddit link itself contains the subreddit names. All Voyager has to do is simple string parsing to get them.
No - you copy-paste a link that encodes the list of subreddits you were subscribed to, you could copy it from another machine entirely if you wanted
