I have to admit to being confused a bit, max (he digressed, futilely attempting to return to the challenge) -- just how are we to "detail the elements" without, in effect, posting a guess as to identity??

I was bit muddled when I wrote that, which certainly did not help. What I should have said was that those who accept the challenge could post something like "when I made my guess, I looked for things like ...". This way, they could train the less discerning among us by showing us what sort of things we should be looking for. Giving specific examples could be done from one's own experience. As an exampe of what I mean, I and all my paternal cousins refer to our common grandfather as Father, a learned family idiosyncracy that is quite distinctive. Were I to attempt the challenge, I could cite my own family's idiom as a "names have been changed" example of the sort of thing I was trying to find. I suspect that all I have done is make my murky post much murkier. Sorry.
