Oh, I see. Browsing their communities has to be done on their instance on the Communities page, I believe. Then yeah, you’d have to copy the community name and then add it to a URL from your instance.
You could browse their “all” by going to their home page and switching from “subscribed” to “all” in the selector above the posts.
The “all” for the instance you’re on is determined by whatever instances that instance is federated with. There’s a link for that list down in the bottom-right of each instance. It says “Instances”.
See the top comment… basically, you treat their community as if it’s a community on your instance, and just append the instance it’s on to the end:
This is the way.
Yeah, that would be rad. Or even just more columns for the communities on the “all” tab of the communities page, and make it sortable.
