Does kbin standardly use "@magazinename@kbin.domain" instead of "!magazinename@kbin.domain"? (asking this as a Lemmy user)
That appears to be the case. I'm on my own instance of kbin, viewing it in a desktop browser. When I was searching for communities with ! and not finding anything, I at first assumed I'd set up my instance wrong and search wasn't working at all. But then I noticed magazines on kbin.social labeled themselves as @magazine@server
, so I tried that for something and successfully added it to my instance.
