Might be a stupid question, but I iust signed up for lemmy.world today and wanted to add some communities from the migration list here. The equivalent of r/anarchychess is listed as https://sopuli.xyz/c/anarchychess and on my first visit to that site I couldn't really figure out how to subscribe... in this case sopuli would be the hosting instance if I understand. Do I need a sopuli account to subscribe and just add that account to my lemmy app? Or did I just not find the right option?
