Apologies as I am new here. Trying to find a way to discover new communities within lemmy. I’m currently using Jerboa if that helps.
Edit: Communities can be searched and discovered through the site by clicking on the header and choosing communities. However, it appears that Jerboa does not have that option yet.
Its in the hamburger menu on the top LHS, you can see the Local, Subscribed, and All feeds. And you can search from the icon on the bottom that looks like a list (second from the left?) from there you can also search communities from the top bar. Hope it helps as well.
