Pingback and Trackback for blogger

http://mymindstalk.blogspot.com/2010/08/pingback-and-trackback-for-blogger.htmlI have spent the whole day today trying to find how I could do a trackback/pingback from my blogger account. Still haven’t found anything that I can use. I thought I would use haloscan, but it is not free anymore. I tried installing GreaseMonkey along with this script - but even that didn’t work. Is there any way we can do that in Blogger??
