Thanks for having us! I'm excited to try this out. I am only just trying to figure out how all of this works.
I have subscribed to several communities now, but when I go to the main page, I still see the generic content that was there before I logged in. How do I view a feed of just the communities I have subscribed to (analogous to the front page on reddit)
There should be a button to view subscribed communities at the top along with local instance communities and all known communities. You can change the default in the settings.
