Click on User CP (lower left end of the box containing your User Name when you're logged in; CP = Control Panel). On the left side of the page that opens are several different boxes, and the second one from the top is labeled Your Profile. The first item is Edit Your Profile.
When you click on Edit Your Profile, the page that opens will have three different sections for you to customize your Profile as you like. The other two items under Edit Your Profile will allow you to customize your Profile Privacy and your Profile Picture.
Another very useful section for customizing your account so that it is just the way you want it is the Settings & Options section. There are many different items in that section that you can edit to set your account up just the way you want it.
I hope that helps. If you still have any questions, let us know.
"Your vision becomes clear only when you look into your own heart. Who looks outside, dreams; who looks within, awakens."
