Then I need to go to my particular instance (lemm.ee)
Then I type manually in my browser address bar lemm.ee/c/<communityname>
Then I go back to https://browse.feddit.de/ and copy the address of the original instance of the community.
Then I go back and add the original instance address to already typed thing in step 4 like this lemm.ee/c/<communityname>@<originalinstanceofcommunity>
Then I can finally subscribe!
Oh my God! Please, tell me there's a better way of doing this!
EDIT:
There is a better way! Solution is to ... use the search function in your instances home page and select community (if it exists already) and search. This way I don't need to go to browse.feddit.de anymore. And links will take me straight the the communities "reflection" in my own instance, where I can subscribe.
When I add !privacy@lemmy.ml into my search field, it doesn't show anything - in fact, it ends up telling me that there are no results. I have to then go into the Communities tab again, and hope it shows up there.
I can see it doing work as I watch the logs. But this is really a little weird/frustrating. I hope this sees improvement eventually! =)
If anyone else on your instance has already subbed, you can "just" visit /communities/ on the instance where your account is and click subscribe.
If you're the first to discover this sub, it's an annoying process. The steps I'm used to (and that are described in the post above) are different than what you described. I'm not sure how much easier they are, but they're what I recommend and have found easiest among approaches I've tested.
You can copy the link to the other community in full (something like instance.url/c/community_name) and go back to your community and go into the search menu. Paste the link in and you'll see the community in the search results. Click that link and you can subscribe
