As this is still a new server the communities you may want to join may not yet be shown on unilem.org. Use a site like lemmyverse to find your favourite communities. Copy the community id eg. !lemmy@lemmy.ml and paste in the search. Wait a few seconds and the community will pop up and you can subscribe. If you still need help DM me or reply in the comments.
I’ll try that, thanks! Could uBlock Origin be interfering? Anyway, I’ll just try harder next time lol.
Some I searched for didn’t show up I believe this is because no one on the instance is is subscribed. I went over to lemmy.ml and searched for the community I was looking for and then copied the contents of the address bar into the search box over here on unilem and I could then subscribe hope that helps at all
