Cannot join lemmy.world. Am I doing something wrong?
I thought if I create an account everywhere in the lemmy universe, it's valid for every lemmy page (like lemmy.world or lemmy.ml).
Apparently this is wrong. Do I have to create an account there again if I want to post there?
You can interact with communities from other servers from your home server. Your posts and replies will be seen there. No need to login on other servers
To elaborate on this, make sure you're visiting the lemmy.world community from your home instance, not going to lemmy.world's URL. Use the search button (upper right corner) to search for the community, and the result will be the link to that community from your instance.
Yeah, this is a downside of federation right now. Too many linking still goes to the target instance instead of loading it in your home instance. I hear Mastodon is fixing this behavior, Lemmy should definitely follow this, imho. (Making hxxps://instance.tld/@\user equal to @user@\instance.tld)
Be sure I have on many mobile apps right now is that clicking links open to the web browser instead of in app.
Your login is unique to the home instance. In effect your username is the full vestmoria@linux.community but the @ portion gets added in when you log in on the linux.community page. There is some theoretical talk of federated identity that would let you use credentials across instances but the logistics of it seems daunting.
You can still read and post to wherever from your home instance, so long as the other server wasn't defederated for some reason.
We badly need federated identify and or at least something portable/nomadic.
If I recall there was talk of migration being a thing in the next major version.
Why?
The biggest issue is the risk that your instance may die. From what I have seen, most instances have given users some warning. But yeah, a few have just disappeared, leaving their users orphaned with no history. This keeps users feeling they need to stay on the biggest instances, putting pressure on them.
A method for allowing users to export/backup their ID and even import it to another instance would be ideal. We (admins) need a way to ensure it is the same user, a unique identifier. Otherwise, you'll get bots importing massive comment histories onto their accounts and faking legitimacy.
I also see this as a way for mods to maintain a ban, so a user doesn't just migrate their account to another username/instance and continue to spam or abuse readers.
You could use the Mastodon-Model, where you can download your data and point the users to the new instance, so the followers migrate automatically
consider yourself lucky
Yes. You are late to the party. Open sign-ups are now closed.
