On lemmy.world (where I'm mostly at) I see local communities getting posts in threads that are clearly for another thread. World still runs on 0.17.3, as the captcha is disabled in 0.18.0 and 0.18.1-rc1 gave issues.

Is this a known issue with federation between versions or limited to the old version?

My main desktop on Debian, left QHD screen, right full HD. (needed the old QHD for remote sorkspace) Debian Trixie with XFCE4, DarcCold style and Adwaita Icons. Didn't do much tweaking, yet. Switched to XFCE4 3-4 years ago after running CTWM since '96. (Still use that desktop for my vnc environment on my main RPi)

I was wondering, did I miss the federated authentication service? When a user has a mastadon account on one of the federated services, it is possible to follow and post on mastodon, react on lemmy and follow lemmy users, but creating a lemmy post isn't possible. When a user has a lemmy account, interaction with mastodon is possible, but to follow you need a mastodon account.

Isn't there an authentication service, so you can create [email protected] and interact wuth all services?
