Can someone explain a little bit about how federation works? Can I log into other Lemmy servers using my lemmy.ca login? Also can I create communities that exist across multiple servers?
I would love to know too. Maybe a link to a Lemmy how-to ? I have a true fear of missing out I think. For example, if I follow /c/hockey on lemmy.ca, do I also get the posts from other instances ? Someone help us ! :)
I've been fiddling around with it a bit. I think the way it works is that you sign up to an instance, and log into a specific instance. You can search for communities on other instances - e.g. ifyou search for https://lemmy.ml/c/memes, which is the memes community on the lemmy.ml instance, you can subscribe to it, even from this instance.
The comments do go across. That's quite good.
So, if I go to lemmy.ca/c/memes do I see the same content as on lemmy.ml/c/memes ? That's the major issue I see but maybe I am mistaken and both "points" to the same content ?
No, but you can subscribe to both communities from your account on Lemmy.ca.
So it'd act like 2 separate communities on your feed.
Ah, then unless I go and search all instances for, say, /c/hockey, these will have different posts. This is a shame.
But thank you for taking the time to answer my questions :)
I believe the idea is that there will be one main established hockey community, and you wouldn't need to create another on another instance (unless you're unhappy with the "main" one). So if lemmy.ca hosts the hockey community, users from other instances would just use it directly. For example the main lemmy woodworking and hockey communities both appear to be hosted right here on lemmy.ca.
I think that's the case. But I'm new here too, so maybe there is some way to search across instances.
It's kinda like how there is the /r/gaming subreddit and /r/games, they post similar content but you cannot see posts and comments from one of those subreddits on the other.
Whenever you come across a community that you're following, like [email protected], that's also hosted on another instance, like [email protected] hosted on another instance, just follow that one too.
