It would be real sweet if you could paste in an instance into the community search, and see what communities they have set up and join straight from the https://lemmy.world/communities community browser UI.
I just found out about https://feddit.uk/ earlier, and being a Brit wanted to join a bunch of the communities and had to use their feddit.uk community browser and then paste the link in one by one into lemmy.world search, and the open up the community in lemmy.world and then press subscribe.
Or even being able to subscribe an instance could be decent, but no doubt a lot more work and resource usage constantly federating new communities across etc.
Yeah I made an account on feddit.uk too, but I made this one first and it’s taking a long time to build up subscriptions at the moment. Once it becomes easier to find and subscribe to communities I’ll start building up my feddit.uk one too.
I use the jerboa app as I’m a phone user, and overall it’s really good except for the community visibility and some other small issues. I’m constantly switching between the app and my browser to go through that process if I only see a link to a new community rather than a post I can just click through on. I’m sure in time these things will be addressed tho
