The community I contribute to the most is the only one. The other same-name communities are dead (or only a couple old posts) and I posted a link to the one I use in the posts. Also, I browse on mobile most of the time, so I don’t see sidebars.
That’s why I joined my local “area of my country” instance. I just need to subscribe to all my communities here and I’ll be good. The app I use (Memmy) let’s you easily switch between profiles on any instance too.
Not sure how to properly post it for everyone, but Shrooms@sh.itjust.works or !Shrooms@sh.itjust.works
