[Nigel Roberts]

Tickling an old thread, I was amused to come across this article.

(Apologies if I'm recycling electrons here.)

I have a strong suspicion that I may have been the author of the 
'strange message to the Zork list' mentioned in this article.

I don't suppose there are any archives of that so I could tell for sure, 
are there??
