I subscribed to technology@beehaw.org, so I can see the posts from here. I did it by seeing a post from my local server (infosec.pub) and going to the community and joining it.

How do I get to other places in the Fediverse, though? I’m on jerboa and want to interact with e.g., https://kbin.social/m/asklemmy@lemmy.ml/t/11331/Is-Lemmy-your-first-time-on-the-Fediverse
