How to edit signature link?

Hello dear sitepoint members,
I am registered in this forum for so long. I registered in Jun, 2012. But I can’t find how can I edit my signature link. Can anyone please tell me that How can I edit my signature?

[FONT=Verdana]If you use the “My SitePoint” link near the top of any page, it will take you to your profile page. In the left-hand column, you’ll find “My Settings”, and under that, “Edit Signature”.

Make sure you read the forum rules on signatures:[/FONT]
