Trick is for bbPress functions, half of them are WordPress functions, just sometimes with bb_ on the front, so they behave essentially the same. A fair few others are just aliases to return data instead of outputting it (i.e. get_forum_link vs. forum_link). Beyond that though, yeah it’s all pretty undocumented, but it’s usually relatively obvious from the name and parameters it takes.

I’d love to be able to help right a bbPress Codex mind you…
