You know that bar some people's layouts have at the top of the page?

It shows an icon and buttons for logging out or going to your friends page?
I think it says Powered by Insane Journal.

Anywho...How do you add that to your layout?
Heck, is it something you can add to your layout?

Keep in mind, this is me. So any instructions would have to be in short sentences with tiny little words. Stick drawings on cocktail napkins may help. Techno isn't always my friend.
