Ron If you don't mind me saying so, I think you "over egg" the GUEST problem.
Surely it is the content of the post which is important, not the identity of the poster.
Very few of us have a clue who the other members of this forum really are. Handles tell us no more than the label of GUEST.
Except for the chance of mistaken identity during debate, which Mr McGrath of Harlow has brought to our attention for long and weary, I see no advantage in having a personal handle other than for egotistical reasons.

I find most of the guests here better informed and more entertaining than some of the "longest standing members" like Catspaw49 or the representatives of the "religious right".....Ake
