I just turned on an option that allows you to customize your personal page that you see when you click on the "My Page" tab up top or someone clicks on your name.
You can customize the appearance including the header section. I just worked on mine a bit and you can get an idea of what you can do by going to my page at: http://6364cadillac.ning.com/profile/jasonedge
To get Started click on 'Settings', then 'My Page' over on left, then 'Appearance' and you can change much of your personal page. If you mess up there are a couple of "Reset" tabs on the same settings page.
Check out my page and see what you guys can come up with.
