although this site allows people to use handles to cover thier identity it doesn't take long to work out who does what job, what hardware they drive and what their experence is
As an example of how easy this is, I once posted elsewhere (a place where I use my real name, nothing to do with aviation) "what's my PPRuNe handle?" and someone came back with the right answer in not-very-many minutes. Going the other way - from my PPRuNe handle to my real name - must be even easier. (I'd be using my real name on PPRuNe except that at the time I joined essentially nobody at all used their real name, and I didn't want to look odd.)
