If you need help with the basics of using Kbin, there's a Kbin FAQ by @dannekrose at:
https://kbin.social/m/kbinfaqs@kilioa.org/t/20459/A-small-FAQ-to-hopefully-help-new-users-to-kbin
The same author has also done a follow-up FAQ for slightly more advanced questions about Kbin:
@feditips my biggest problem with Kbin/Lemmy is that, and this may sound weird, they're trying too hard to be a 1:1 Reddit replacement. Having separate servers but also further separating by "magazines," but then connecting them with a Reddit-like UI seems like a mistake. I feel like there might be a way to do it, but at this point it feels awkward.
If you have a better way, let the developers know!
@feditips I wish I did. I'm not a programmer nor do I even have a well-developed idea of what a I'm looking for. But I think that, while mixing different servers on the same home page is good for visibility, at the same time it's kind of a mess. I suppose I'll have to play around with the platform more to get a better idea of its potential.
