Yes, it has been dead for a long time
KDE & Plasma users
KDE is an international technology team creating user-friendly free and open source software for desktop and portable computing. KDE's software runs on GNU/Linux, BSD and other operating systems, including Windows.
do you know if the kde team said anything about this? I think I'll ask them later.
I talked to carl schwan a couple of times when I still had an account there and I noticed the issues. sometimes login was not possible, then for weeks the instance did not update/sync with other instances and was therefore basically unusable. eventually I moved on
Weird. The URL you have does that for me too, but my subscription link works fine as well as just searching the community and opening it.
It's a quirk of how Lemmy works that each instance has its own cached copies of every community that any user on that instance has subscribed to. So you can keep viewing old posts, even if the other instance hosting the community is temporarily down, or even doesn't exist anymore. It looks like the community was getting posted to almost daily until 18 days ago.
