It's becoming more common for blogs to have their author's comments highlighted in the comments after a post (I was reminded of this while viewing Brian Jones's blog on Open XML - see http://blogs.msdn.com/brian_jones/archive/2007/01/19/passing-the-openxml-sta... for an example).
How can I do this in Drupal? My guess is that is requires some PHP in template.php plus an extra bit of css but I'm not sure of the best way to get this done.
Thanks in advance,
Tim
