I am no longer using a standard email program. When I reply to a message,
I contstruct the reply by manually editing the message being replied to.
I make mistakes when I do that. One of the mistakes I make is forgetting
to update the From: address. I'll try to be more careful.

That is my plan. I expect to buy copies of the revised report and the
Haskell Road to Logic,... book I got through interlibrary loan. The
revised report is available online, but I find reading a physical book
handy when I want to take a break from the computer.

At some point I am going to fix that problem in my copy of hugs.
