You can select Home -> hamburger button -> Communities, but that just lists your subscriptions. I want to be able see all available communities for the instance I'm logged into.
It's available using the web UI, but I can't figure out how to do it with Jerboa.
lemmy instances are not automatically connected
at least one user must be following a community for others to search it
I found a tool to basically create a bot account to add servers. It uses the lemmy api. I took this idea and created one as well (not sharing it’s terrible) but it went through all of my approved instances and all of the communities and subscribed to all. I now have 2300+ communities. That I can see from my instance
if you just want to search for new communities to subscribe to then check out https://browse.feddit.de/
from there you just copy the link and paste it into your instance search bar, hit search a few times if it doesnt show up. then when it does I usually open that community in a new tab, you will have to hit subscribe a few times if it stays as pending, just keep hitting subscribe until it says joined.
if the subscribe button doesnt load for whatever reason Ive had luck clicking the name of the community so it reloads and usually the subscribe button shows up correctly
