You just can't get good staff these days :-)
My typist (that's me) missed a crucial sentence or two when transferring
hand-written notes to email.

> different - and different machines:
if my 'ID + last-event' is in his history database - his entry is later
ACTION : add his entry to my database
if his 'ID+last-event' is in my history database - my entry is later
ACTION: add my entry to his database
if all data fields are identical - skip, no action needed.
