Digg for Backlinks

I've searched around here but have yet to get a real explanation of how to get the most from posting a link on a Digg comment.

Would someone share how to properly embed a link in a Digg comment?

Thank you

here is how

diggdotcom
popular page
look for most recent 365 days click it
its pr 6
click comments
and in the box it says no html please
enter your website url?
you can even leave a coment on a comment

anyone else have better idea?

i quess post a real comment working your url into the comment
