Probably possible but not implemented. That's more or less just a UI thing.

Thank you for posting this, as you seem to have more knowledge of the underlying protocols than i have. Had some visions of server takedowns and meltdowns. I have little idea how the protocol works but i'd imagine that account migration/replication would not be such a big deal to implement, and communities are already being replicated, no? As a work-around.

edit 2: Before anyone gets confused by this comment, here is some solution. The examples here are how a web browser displays the URL in the address field. For a link to work in the federation, the browser must be made to assume we want to link to another webpage within the same domain (that is, the server we are logged on to). This is done by omitting the domain from a HTML referance. Of course. It's W3C standard. See this post which clarified it: https://lemmy.ml/post/1168136.
... unfortunately, links to federated posts and comments are still broken because posts synced to other instances get a different ID than the original.
end edit 2

original comment:
"beehaw.org/c/community@instance.org" -- example: beehaw.org/c/lemmy_support@lemmy.ml
or lemmy-specific syntax that will bring up a list of communities known to your instance as you type, and choosing from there will make it a link: "!community@instance.org" -- example: !lemmy_support@lemmy.ml
... unfortunately, this dosnt work for lnks

edit: seems that i just uncovered a bug systemic inconvenience, because the link that is generated leads you directly to that instance's webserver ... which we don't want if this is posted on our home instance (because the link should actually enable us to post on that remote instance). otoh, if we are viewing this from a third instance, then a link "instance2.org/c/community@instance.org" would likely not work at all. (right?)
check: beehaw.org/sopuli.xyz/c/lemmy@lemmy.ml -- nope!
check: /c/lemmy@lemmy.ml -- yep!

May i ask what your reasons for not signing up at beehaw were? I'm still making up my mind. The main reason i went for it (besides one of the owners being very verbal about their philosophy), was that it has some size, which gave me trust that it would not suddenly disappear together with all their user accounts and content. Account migration sadly is missing which is a curious omittance. PM welcome if you so wish.

Ahaaa! Yes that is what i missed. It still lacks listing all communities at an instance and some other general functionality i will not iterate here, but a way of subscribing through Jerboa was what i wanted. Thanks!

Ooh ... excuse my slight neurodiversity. I guess i'm just not a part anymore of a sickening society. Went to other places on that other platform the short periods i spent there.

Appreciate you taking your time to be so verbose. :-)

My bad, took the wrong English word. It should be verbose not verbal. I found the approach attractive, to address the issue of people camouflaging hostility as rational discussion, when they are actually following antagonistic believe systems. As from the first "philosophy" post linked from their sidebar:
What is Beehaw?
Beehaw is a Community
A few thoughts on Beehaw’s design
At the time of this writing, though, i have already changed to a different server, because i got it that the place is going to attract a US-of-A style ryrannic PC mob which will exert its own hostility, in their need for a safe space, believing a demand for "niceness" masking -- whatever that means will not be up to discussion -- will do. An echochamber that i will not be part of. The most fun moments on Reddit are often not so very "nice" but rather dirty and snarky. :-)

Seems that it doesn't have a list of communities function, or did i miss it. Only my subscriptions ... meaning i'll have to find that on the website for now and subscribe anywhere even if i'm just reading?

I'm reading that you seem to be confused by the naming of some server instances in the network which is indeed called "Lemmy". One of the servers is called "lemmy.ml" (that's where the main developers are at home and it's currently the one with the most users but that might change). Another one is "beehaw.org". Both and a whole number of others are part of a so-called "federated" network, they share their "communities" with each other. So, although you are registered on beehaw.org, you can as well post to a community at lemmy.ml etc.

Wow thanks for the reply. Yes i knew i can omit it but wanted to mention both explicitly. That was one thing i never knew on Reddit, if users get notified when i "@" mention them or if stuff got cross-posted when people mentioned the r/sub. I feel a bit idiotic now, although i'm technically knowledgeable. Just not scial media adapted.

One of my concerns is about a real de-centralised system not being implemented, as i learned. Migration of users and communities is not possible. Therefoe partial meltdowns are still possible.

Community search: yes i know and used it. It's just not useful if one doesn't exactly know what keyword to search for. An index by general topc would be nice to have. I was thinking about making a sorting thread but really, a subforum would not be the right place for it.

Migration of data ... well too much OT discussion coming to my mind.

Yep the software license would not be so relevant, that's right.
I believe the word "wiki" pre-dates wikipedia --> https://en.m.wikipedia.org/wiki/Wiki

I imagine https://beehaw.org/c/support is a good place, but don’t quote me on that

Seems to be a place at least for general discussion on this topic. Such questions have already been asked there.

Most honeybee breeds aren't actually yellow and black but rather dark brown and grey. Some breeds may be in part orange/yellow and grey, either the odd individual or whole hives. An orange/grey variety might be the preferred breed used in your area, though. The stylised insect used as an icon here looks more like a wasp. :-)

@JakeSparkleChicken@midwest.social @russjr08@outpost.zeuslink.net Thank you, this can also be info for others. I'm afraid this is going to be community fragmentation anarchy. It's already not easy to find subs without a categorised index ... and then, hopefully there will be ways to move users/subs between servers. But let's see how this matures.
... damn how do i make this link and notify more than one user ...

Yep i read the first part. That was part in my decision making for sighing up on this server. Now i'm getting around to reading the second part. Thanks for explaining your take on what you call "rationalism" because else that would have left me questioning. Am i right in taking the term "centrist" as political? Would have to educate myself on that.

The Wikipedia software is used by many institutions. When i still worked in uni, we tried it for our group internal documenting. In the end went for a less complex wiki software, though. :-)
