Why isn't it a rule on this forum that people be required to post in their public profile at least the basics of what empowers (or not) them to comment? Even I list my pitiful aviation accomplishments--the reason I rarely put an oar in--and it really annoys me that other commenters condescendingly list simply that they "live somewhere on the planet" and then hold forth on whatever issue amuses them.
Certainly they needn't list their employer or home address, but why not just a certificate or type rating?
I suspect SNS3guppy is entirely legitimate, but why the cat-and-mouse game?
