Roleof, do you think you could stop sending HTML messages and use
plaintext instead? I usually skip over your posts because your font
is so small and hard to read that I don't even bother.
If you send plain-text messages (which is the norm on programming
mailing lists) then you leave it up to the e-mail client to render the
text.
Yes, I could turn off HTML on my end, but that is a pain and breaks
messages that I legitimately want to be HTML.
Thanks,
-Luke
