This is not a private pilots forum.
Private pilots means something different in the industry to what you infer. It means guys and gals flying for fun and not for air transport operators. Thus you are correct in more ways than you think.
The prime raison d'etre for PPRuNe is to serve as a conduit for 'professional pilots' in the many different guises that takes. It also serves other industry professionals.
A secondary role is to provide a means for non industry people to interface with the industry. Quite often this will mean that day to day business (which appears to non industry folks as shock horror stories) will get moved to a forum where it is more appropriate. A sleepy backwater if you will .... because to those of us in the industry it is a non event. It may also attract scorn from professionals who see their industry under attack and scrutiny on a regular basis, but also hopefully will see professional people providing the answers to the questions raised.
