Does this forum have any documentation of how it works?

@BrenBarn

that doesn’t explain the footnote syntax (which was something I remember having to hunt to find before)

Okay I had to hunt down that one too now, and I found it here Discourse Footnote - plugin - Discourse Meta.

I added it to that intro post Python Discourse Quick Start.

@BrenBarn

Anyway, I think it would be nice if the forum had more comprehensive documentation.

Yeah definitely would be nicer to have a full documentation instead of wiki posts.
The closest thing to that I can find is the meta discourse forum Documentation - Discourse Meta
