You have to prefix the community with an @
, so search for @washingtondc@lemmit.online
You go up to the magnifying glass icon on the instance that you want to subscribe on (not the instance that the magazine or community actually belongs to), then that's where you'd search washingtondc@lemmit.online
It should appear and you should be able to follow it. If you are the first person to look up that magazine on your instance it may say that there are zero posts and that the owner of the magazine is your instance's admin, but as long as the name and the magazine/community icon looks like you're expecting you can follow it and it'll start federating in new posts over time.
Hmm thats what I tried. You can see the two places I searched in this imgur album https://imgur.com/a/ZN1OGYT
