As a club we've been email- and web-literate almost since it was
possible to be that way,

That would not be us. I am the only instructor who has successfuly
scheduled a multi-day airplane rental. :-)

Interestingly, most of the instructors are young, but are almost
computer illiterate. One came to work one day depressed because his
wife had destroyed his computer by getting a virus. All he got when
turning the machine one was a black screen with a cryptic error
message. He brought me a copy of it. It said: "C:\Windows". I
hurt myself falling out of the chair laughing.

phone / voice command access turned on for the first two years of
use -- and no one ever used it.

I don't blame them. I hate voice systems, as a rule. But when I want
to check my bank balance, I use the automated telephone system....much
faster than logging in via the web.

It typically takes me seconds to enter a new entry in our system.

Takes me several minutes. You have to reserve the times by clicking
on option buttons in 30 minute increments. Four buttons for a 2 hour
flight. I go click, click, click, click, and then wait. After a
second or two, one option button lights, pause, then the second,
pause, third, pause and finally fourth.

Well, I'd have to say that with a club attitude like that, they're
probably right. Sounds like a self-fulfilling prophecy, to me...

Yes, you're right. That's why the decision-makers should have
involved everyone who would use the system.
