I think it would be a great idea to make the help section public and link in with the features pages.
This way we (Monzo and general users) can start linking users of the community out to specific links and pages of truth. This may prevent as many duplicate posts and get people more used to using help for self service.
So for example
—Page part 1 - details of the feature
—Part 2 - FAQ
—Part 3 - help (already showing overdraft results)
Hopefully this makes sense.
