@normis has thread about the the manual.mikrotik.com docs. But sometimes a potential doc issue arrises in the forum that perhaps should be considered when looking at "documentation improvements".
My idea is that you'll add a some new category of flag 
for "consider for documentation", in addition to the more negative illegal/inappropriate/off-topic/etc ones. This might another channel for "feedback" on docs, even if the action is ignore, there is at least a list to see if more similar one come up.
While some feedback buttom/mechanism on the manual.mikrotik.com page themselves be another/better avenue. Having some channel to flag forum post to highlight some need for "better docs" might be useful.
