The smart comments plugin written by Patrick was not compatible with the newer Wordpress 1.5 version which I'm currently using. So I opened the file, modified it, and voila! A new version is born.
Feel free to download the Smart Comments Plugin v 2.0 here.
Instructions:
1) Put the file smartcomments.php in the wp-content/plugins folder.
2) Activate it by going to your Admin -> Plugins page.
3) Then, in each of the index.php and archive.php files, find this line:
< ?php comments_popup_link('No comments »', '1 comment »',
'% comments »'); ?>
4) Simply replace comments_popup_link with smart_comments_popup_link and you're done.
Hope it saves you some time!
