Im joining in on the reddit ditching thing, and was kinda worried at first that i wouldnt be able to like use it the way i did reddit as it feels like a whole new place, but after engaging with posts and people and actually being a part of lemmy rather than being lurk mode all the time i was pleasantly surprised with how easy it is to become a member of the community, theres a reasonable amount of subs (or whatever the other word for em is) that fit my interests, enough linux content and shitposting for my liking, and the overall random posts made by people equally fed up with Leddit. (also i admit i used reddit a little cus there was this post on the fedora sub showing how to fix a sound issue i been having after a recent update)
If kbin is like lemmy, then to add new communities, you have to do the following:
Go to your instance in the browser. I.e., do not use apps like Jerboa.
Go to your communities tab (magazines?) and set it to “all”
Search for [email protected] from your kbin instance. It will not return any results, but it will do the trick.
Now the 404 will have disappeared for you and all other people in your instance.
Instead of typing the url, search for only skincareaddiction without “!” and “@sh.itjust.works” and it should be there.
