I tried to make this last night on the phone, but it didn’t work. Lemmy is a bit finicky with the “Language” field of a community.

I’ll make this for you when I get in front of a computer.

Edit: the problem wasn’t the language field. It was the name. Community names only support lower-case, and I copied/pasted BrisbaneTrains from here. It didn’t work, but the error wasn’t visible on the small screen because I’d scrolled too far down.
