How do trackbacks?

Even i am blogging for more than a year, and never ever heard of that term... And please please do not post link, waste of time , for all of us..

I am unsure what you are asking. I have been using blogger for over a year, so I can most definitely help you, but I don't understand what you mean by "where is it?" or "trackbacks" And FYI, don't ever post links to your blog on here. It's a great way to get your thread deleted and to have your account here terminated.
