[BALUG-Admin] Mailman, web scraping, case-preserved email addresses

[Michael Paoli]

And turns out I can also access and save the case-preserved
email bits.  Turns out it only explicitly shows that on the pages
of members that entered their email address using one or more uppercase
characters within.

Yeah, I know, RFCs & Internet email addresses, it is
(*strongly*?) recommended the local part be treated as
case-insensitive, but it is not *required* to be treated
as case-insensitive.  And of course the domain part (DNS and all that)
is case-insensitive (though DNS generally *preserves* case, but is
mostly insensitive to case for matching).  And "of course",
users/members/humans may wish to (generally) see/show their
email address as or in form with mixed case, though too, they may
often wish to type it in lowercase only).  Interestingly, overall
common style and general practices tend to change(/evolve?)
over time - I think all lowercase is becoming increasingly
common for email addresses in entry/presentation.  (And
other random bits, like email instead of e-mail,
using . to separate portions of phone number rather than -).
