A search I was doing dug up this old gem, involving a discussion between Gerald Edgar and I over a Maple problem 16 years ago!

Easy challenge: improve on my solution to Gerald's problem.

History challenge: my email address shows as wmsical!jjcarett@watmath.waterloo.edu.  Can you puzzle that out?  That is really two questions, a) how is that an email address and b) what is 'wmsical' ?

At the same time, I managed to dig out the original Internet registry for Maplesoft! (search for maplesoft). 

Super-difficult history challenge: I did not come up with the name 'maplesoft', but the person who did has in fact posted on mapleprimes.  [I'll have to ask permission to post the answer if no one gets it.]
