Hi Comrade Gibby,
If you click on User CP at the top left of the page, you will see that boxes drop down, you can then click on Signature and add the details you want.
After that you will see your efforts depicted in your posts and having seen other users profiles you can adapt it to your style. Also if you go further down the page as you are editing the signature you can add images and icons.
I hope that helps, Good luck and Nice Car! Stu
