Perhaps not, but you should be concerned about them.

That amendment is correct. We might not agree on what is
"appropriate" though. I am definitely out of step with a now substantial
part of the Lynx User Community on the level of understand about Lynx, HTML
and HTTP they should be expected to acquire in exchange for making Lynx
available to them.

Thank you for providing a non-lacking bug report about that.
It's fixed in tonight's update.

My indent is that color support will be turned on if the
-color switch is used, if the COLORTERM enviroment variable is set,
or if slang's SLtt_get_terminfo() decides that this is a color-capable
terminal, even if show_color=off is in the .lynxrc file. It is also
my intent that users with personal accounts, but not necessarily shell
accounts, and not necessarily able to include the -color switch or
to get a sysadmin to fix up a bad terminfo/termlib entry for their
most frequently used terminal, be able to save show_color=on in
their .lynxrc file, and have that act like the -color switch. That
means that if, on occassion, they connect with a non-color terminal,
they must invoke the 'o'ptions menu and set "show color (&)" OFF.
Conversely, if on some occassion they inadvertantly end up saving
show_color=on in their .lynxrc and normally connect with a non-color
terminal, they must acquire sufficient understanding of how Lynx works
to know that they should invoke the 'o'ptions menu to set and save it
back to show_color=off. It is also my intent that for anonymous accounts,
the default "off unless SLtt_get_terminfo() thinks it should be on"
behavior be retained, that when it's wrong about the user not having
a color-capable terminal they simply invoke the 'o'ptions menu and
turn it on, but that they not be able to save that setting, and thus
change the "off unless SLtt_get_terminfo() thinks it should be on"
behavior for other anonymous users. I think those intentions are
realized in tonight's update, but if not, non-lacking bug reports are
