The thing is that we are a community and I feel there is quite an influx of 'experts' who come along and try to 'enlighten' us and 'educate' or 'advise' us, with no real intention of being part of our community.
I have no objection to anyone who comes along, joins in with threads, mentions interesting facts/techniques/knowledge they have, etc. I mean, taking Moondog as an example - she comes along, gives fabulous insight to discussions and it never feels like she's walking into the thread and saying 'righto, expert has arrived, take a seat and listen up!'
I do object to people coming along and advertising their services to parents who are at a vulnerable stage in life, especially when MNHQ themselves say 'no advertising'. If people have something useful to contribute, they can do it on the threads in question and then everyone can benefit from that knowledge and insight.
Or, they can offer to give assistance by PM.
It was only a few years ago that there was a massive hoo-har on MN because a certain (much loved) reverend dared to use her title in her name and people felt that there was a risk that she could be a hairy trucker 
I wonder how she is...must check.
