[ih] Any suggestions for first uses of "e-mail" or "email"?

[John Day]

Not off the top of my head, but there were articles in conferences at the time on Tymnet and how it worked internally.  The protocols were (I believe) mostly homegrown.  What I remember about Tymnet was that they were pretty slapdash. They never saw anything coming until they ran into it, so even something like flow control was a retrofitted kludge.  At least that is the impression, I had at the time.

Take care,
John
