I’ve also got all of my domains in Porkbun. I don’t use their nameservers though. I usually use cloudflare for that, so you could look into them, too.

Is it kind of like KBin, Lemmy, and Mastodon are the frontends to ActivityPub which is the backend? But I wouldn’t be able to sign into “Mastodon” with my Lemmy account or vice versa, right?

So KBin isn’t Lemmy? But it federated with Lemmy? Also, I see Mastodon federated with Lemmy, but what’s the point of that?

Well that’s nice of them
