When the arguments are displayed like comments at the bottom of the parent node, currently, the full text of the argument is shown.
This can be a problem in case of long arguments.
In case you want only a teaser of the argument to appear (with the "Read More" link to see the full argument), you just need to change the node_view statement in procon_views.inc at the bootm from:
$output .= node_view($node);
to:
$output .= node_view($node, TRUE);
The second parameter $teaser is now set to TRUE.
