Although Discourse is advertised as a mailing-list manage-
ment system, it is certainly is not equal to the task: I see
that is has distorted my message by collapsing consequtive
spaces used for justification and replaced ASCII dashes con-
sisting of a pair of ASCII “minus” characters by single mi-
nuses. Futhermore, it has excised my signature and committed
the gross offence of displaying my e-mail in a proportional
font, whereas hard-wrapped pre-formatted text must always be
displayed in a monospace font. If my original post looks
awful, it not my fault.
