Gengis,
I think you pointed the good (bad) points.
confidentiality is also a problem.. A healthy and communicating community is also a key for success. I would add that Europ misses a good reprentative organization to promote and educate air people, but also to provide the gyro people appropriate communication, safety, building and training issues. Alas, every valuable person, most of the time, tries to get in gyro-business and retains the infos and doesn't participate without commercial intentions ( see tha MAGNI ad left on this thread , thanks mr Magni, we know who is magni and where the magni comes from..).
Thank you
