Click "Hide All" then search for the instance you want and enable that one.
Click the house icon at the top of the page and enter your home instance
Now you see a list of all communities on that (or multiple) instances, and clicking on them takes you right to that community on your own instance. It's the best way I've found.
Wow, can I just add all the communities from mander.xyz and then filter out what I don't want? I like the content but I'm starting to try to consolidate my testing IDs into one instance. It's a feature that I have to purposely go add other communities on other instances and the only "defaults" I get are the ones on my local instance?
I wonder if there is a way to have a feed that is startrek.website + mander.xyz but exclude other non-sciencey discourse from ala .world or .ml. "All" right now does not options to filter those out...
You have to subscribe to the communities you want and then do "Subscribed" instead of "Local" or "All". I don't know of an easy way to mass subscribe though. The easier way is to click in "Communities" and search/subscribe those you want. You can search for communities in all instances there.
