This plugin filters the sitewide comments feed as well as individual post comment feeds.
Upon first-time installation and activation, all trackbacks will be removed from the default WordPress comments feeds. 
You can override this behavior on the options page and also use the comments or trackbacks only feeds described below.
URL for comments only feeds: add the variable “comments” to your feed query string.
<ul>
<li>http://mysite.com/comments/feed/?comments</li>
<li>http://mysite.com/?feed=rss2&withcomments=1&comments</li>
</ul>
URL for trackbacks only feeds: add the variable “trackbacks” to your feed query string.
<ul>
<li>http://mysite.com/comments/feed/?trackbacks</li>
<li>http://mysite.com/?feed=rss2&withcomments=1&trackbacks</li>
</ul>

Separate Feed Comments and Trackbacks

Remove trackbacks from your sitewide and individual post comment feeds, and/or have alternate feeds for comments or trackbacks only.

Adds a template tag ‘trackback_template()’ that displays the list of trackbacks for a post/page. This is especially useful for 
sites that are displaying the comments using a seperate service (i.e. Disqus).
<h3>Modifying the template</h3>
By default the plugin displays the trackbacks as an unordered list inside a div with the id “trackbackslist” with a h3 heading “Trackbacks” above the list 
Alternatively if you’re comfortable with editing HTML & PHP you can add a file called trackbacks.php into your template folder and the plugin will use that to style this list. 
The file trackbacks.php in the plugin folder contains the default code & is a good starting point for customising your own template. Copy it into your 
template folder and it will be used instead of the default file.

Trackbacks Template

Adds a template tag to allow you to display only the trackbacks for your posts/pages.
