Hello all!

Came to Lemmy from Reddit as I wanted to be a part of helping the fediverse & Lemmy grow. As someone mentioned on here “be the change you want to see”. So here I am! However I’d like to fully understand the fediverse so I can explain it to others and help them join.

I understand the concept of the fediverse but what I’m struggling with is the instance part. I know an instance is a spun up server, and I’m assuming it’s a copy of the lemmy source code, for example, which means it is its own contained version of Lemmy. This instance sets it’s rules, creates its own sub communities etc. You join the instance that relates to you the most.

But does that mean you can only post in that instance? I know you can follow users etc from another instance, but you can’t post in their instance without migrating your account there? Is this the same for mastadon, where you can read / follow users, but cannot post?

The example im thinking of is say there is a sub community on your instance for gardening, but you find out another instance has a bigger, more involved sub community for gardening. You want to participate there, that would mean you need to join that instance to do so? Would that mean multiple accounts for multiple instances?

If there is a handy FAQ, or a video, that helps explain this that would be great!

Really excited to be a part of this and looking forward to understanding it better.

    Welcome 👋

    You can post and comment with your account on any post or community on any server as long as the servers are federating. For example I have my account on feddit.de but I am now commenting here on lemmy.ml.

    Usually you can just search for a community in the search bar and then create posts there or browse their posts and comment.

    For new communities on different instances, they have to be “discovered” first by pasting the URL to the search field. For example if you want your server to list the hamburg community from feddit.de you copy https://feddit.de/c/hamburg and then paste it to the search bar. Then it is accessable to all users of your server.

    I hope that helps a bit understanding how it works. If something is not clear just ask ^^

      @nachtigall @WorriedGnome In addition to the above - you can also post from Mastodon!

      It is currently one-way: Mastodon users can follow Lemmy communities and interact with posts; you can’t follow Mastodon users from Lemmy.

      But it’s super neat that it’s able to do that at all! For example, I am replying to you from my Mastodon account. If you hit the little “Fediverse” link next to my name, you’ll be taken to my profile on my Mastodon instance.

      This is because both Lemmy and Mastodon are part of the Fediverse, and thus can understand the data they send to one another. So to me, your stuff shows up as toots in my timeline… and to you, this is a post on Lemmy!

    Well, I’m replying from my own single-user instance which may answer your question :)

    But yes, you can sub from one instance to another’s communities no issues. The only exception is for instances your instance doesn’t federate with, which is basically an admin-level blacklist.

    I’m subbed to communities across at least a half dozen instances from my own one, and it works perfectly fine for both viewing and posting.

      There are plenty of ways instances can not federate beyond server blocks.

      Federation is an active behavior, not a passive one. Someone needs to subscribe to a feed from a other server in order to actually federate. If no one on your instance - in this case, you, since you’re single user - has subscribed to a user or group on another server, then you won’t get that content.

      The exception is if you’re subscribed to a relay.

      You can easily set up a Lemmy-based site and have it operate in isolation without setting any server blocks or turning off federation. You just need to not interact with other sites, and remain off of the radar of people on other sites so they don’t try to interact with yours.

      You can participate in communities on federated servers outside your own (as you can see, I’m posting from a beehaw.org account).

      Say you wanted to post something or leave a comment on the technology community hosted at midwest.social. You can type !technology@midwest.social in the Lemmy-ui search bar, you can go to the URL your-instance.com/c/technology@midwest.social, replacing your-instance.com with lemmy.ml or whatever your server domain is.

      This allows you to stay logged in on your home site while browsing the other server, and you will make comments using your home server identity. If you did want to make another account on that server that works too, in order to see more relevant content on your home (like saying “Ope!” a lot on midwest.social) or that server could better match your philosophy.
