Ian,
You raise a very valid point on which I would like to comment.
For NCCA Directors, contributing to internet forums is a difficult issue. Likewise for manufacturers. Not only would they be giving personal advice and opinions, but much could wrongly be regarded as NCCA/Manufacturers standpoint or policy. It is wrought with problems and ultimately, many forum members will remember what they regard as negatives and fail to recall positive points. The NCCA and manufacturers end up losers.
I hope Derek Bolton shares my view on why we were different. When I joined the NCCA's Board of Directors, Membership was static. Our roles within the Association were primarily concerned with IT, Marketing and Media (initially Derek and later myself) and membership (me initially). With the knowledge of the board, we decided to embrace all that the forums had to offer our industry and keep ourselves involved. Basically, we took the Association to the industry on a daily basis rather than meet them every two years at the Cleaning Show. We initiated the Technical Roadshow format which started with an event I organised at Dowding and Plummer in Birmingham. This format has been developed to now include Factory Visits and the NCCA Technical Workshops. I would suggest that this programme has been a contributory factor in a membership increase of, I would estimate, about 35% during this time.
Our forum involvement has, as we could have predicted, been fought with perils whereby hindsight suggests we should not have become involved, but we were prepared for that. But there have been many, many occasions where we have had to keep quiet and not comment. That is VERY hard to do.
Safe and happy cleaning

Ken
