I think you hit the nail right on the head when you used the phrase "irritating pop-up". That's Fred Steer exactly, apart from the fact that he seemed to have cornered the world market in exclamation marks. The guy was also almost single-handedly responsible for keeping going the most pointless and boring thread on any forum anywhere in the known world (was it "BOF's" or something like that? Over 500 postings and 10,000 hits............aaaargh!!!!!!!!!!)
Having said that, I always suspected that someone was having us all on; rather like the late Peter Cook, who used to phone up a late-night local radio program when he was drunk and pretend to be a lonely Norwegian fisherman called Sven. I wish I'd heard those calls; the man was a comic genius in my book. Has anyone got any tapes of them, I wonder?
As far as the real identity of Fred Steer is concerned, I reckon Anmo knows more than most...........................
