>> Figured it out. Can you comment on the code below? Thanks. -- [[MarceloMagallon]]
So, I have some code, included below. For some reason that I don't quite get it's not updating the wiki page after a submit. Maybe it's something silly on my side...
What I ended up doing is write something like this to the page:
[[blogcomment from="""Username""" timestamp="""12345""" subject="""Some text""" text="""the text of the comment"""]]
Each comment is processed to a <div> with a <dt> and the text inside it. In this way the comments can be styled using CSS.

The above produces a page that looks like this:
sub preprocess (@) { #{{{
my %params=@_;

IkiWiki::filter($params{page}, $params{text}));
$from=exists $params{from} ? $params{from} : gettext("Anonymous");
$date=localtime($params{timestamp}) if exists $params{timestamp};
$subject=$params{subject} if exists $params{subject};
Subject: Pi
$r = qq{<div class="blogcomment"><dl>\n};
$r .= '<dt>' . gettext("From") . "</dt><dd>$from</dd>\n" if defined $from;

A comment...
Questions:
* Notice how this assumes that the page it's writing to is in mdwn format.
* What to do about the bit marked XXX?
* What about special formatting? Is mdwn enough?
