Forgive the reply in English. Have you worked it out yet? I've only started using trackBack lately myself. It's hard to explain but if you try it out it's actually quite simple.

The other day I wanted to write about one your posts on my site. If you'd had trackBack enabled for that post then I could have pinged your site/post at the same time as posting my new entry.

Then, my new entry would've shown up as a link at the end of your post. I guess it's like a comment but with a link-back, or 'trackBack' to someone who has written something related or inspired by your post.

Did that make any sense?

Thanks, I know its simple I've been just too lazy to turn my brain on these days.
