NFL

I'm just one or two steps ahead of you, I'm still figuring it out myself. I think right now it's definitely annoying to find communities, but in a few months it will become much easier. Once certain communities get big, it should become common knowledge where to find them. There is actually a tool at browse.feddit.de that I used to find the other nfl community. You can go there and search for anything to see if there is a community for it on another instance.
