I think Geoff's suggestion was a good, open request for the sharing of beneficial information.
However, as other contributors have pointed to, this could be open to abuse by others who read this site who are not from a background of equipment maintenance, but not necassarily Dyson engineers Darren
Things like access codes to higher level functions could be made available, and as we all know the night shift have a lot of spare time on their hands to practice the art of "let's see what this does"
We're not strange, protectonist or extreme Darren, just mindful of the harm that can be caused by having dangerous information in the wrong hands.
