Tracking back comments

Blogger doesnt have an inbuilt support for comment trackback, I tried adding the functionality by using greasemonkey (a user script manager for firefox) and downloaded additional plugins for supporting trackback. But I was not successful. If any of you have succeeded to add trackback facility for blogger then I NEED YOUR ADVICE.

The following link provides instructions on how to download greasemonkey and scripts.
