Removing parts of a content type so, I was trying to get rid of the comment title and there is a lot to read about that on the net, but I still had my issues getting it right, so I came up with this, but I believe there should be a better way.
What is the best way of doing this:

function theme_preprocess_comment(&amp;$vars) {
// Remove the comment title
  $vars['title'] = NULL;
}
You can set your content type to not use comment title by unchecking "Allow comment title" under the settings for your content type.



Then I would copy comment.tpl.php to your theme and customize the output there instead of just unsetting the title value in theme_preprocess_comment().
