. . .a subject I've been intending to raise for some time, which is whether or not we have any other regulars here (or lurkers/newcomers for that matter) who are interested in ciphers and cryptography, which to me seems a natural extension of an interest in writing and writing instruments (possibly, of course, only because it's
my interest.

).
Thanks Chris- by the way, I've tried emailing you back in response to your gracious missive and I keep getting it bounced back. Can you email me here:
tcmcare @ aol.com (remove spaces)?
Cheers,
Jack
