suggestion: how about an option to let the comment area start with i.e. 5 lines instead of the 1 line it starts with now?
on my homepage with a custom template, I use this to load the comment form:
<?php $withcomments = true; ?> <?php comments_template(); ?>
and here your plugin seems not to be active while on any other page/post it does work.
currently live at http://pacura.ru please have a look.
