How can I alter the 'submitted by username' for a comment? I am rendering comments on my site. I am using the Zen theme. If I remark out &lt;?php print $submitted; ?&gt; in comment.tpl.php the 'username replied on' part is no longer rendered. But I don't want to remove the whole thing - just the 'replied on' text. I can't work out how to alter this bit. Thanks

In Zen comment.tpl.php it reads: '$submitted: Submission information created from $author and $created during template_preprocess_comment()'. Presumably, somewhere there will be: $author . 'replied on' - and this is what I need to alter.
Solution

A solution is to not use $submitted, but to use $author and $created separately in comment.tpl.php.
