Yeah I'm hoping that comes soon, user manageable merge lists so I can deal with nice.place/c/Australia and fun.people/c/Australia but not echo.chamber/c/Australia
I think it makes sense to add a general Australia community on this instance, with the same vibe as /r/australia. Yes there are a couple of communities already on other instances, but they are not active at all - mostly 1 person posting a bunch of stuff.
If all the Aussies are going to gravitate to this instance for all the other communities, I'd rather have everything under one roof.
