I think I wrote “…Of course make sure you respond properly in due course to any matter that has substance…” IE. Sometimes an EC has to deal with someone who is being unreasonably difficult. Other times the EC should be grateful that someone has brought to their attention some serious matter that should be attended to promptly.
My experience on ECs has tended to be that owners who do actually have some reasonable matter that could or should be usefully addressed by the EC are often shy about bothering us. In contrast those with unreasonable gripes are often less shy. IE you get all sorts. The EC has to try to get it right.
