Personalizing your Profile!!!
Basic HTML will work in the "update" portion of your profile. Just throw it in there like you would if you were building a web page (but you don't need to add in the tag, etc) just start entering the code.
If you ask the OH staff to update your profile, you'll be on a waiting list, as it's all done by volunteers (I want to volunteer, but I need to wait until I have some of that free time stuff). Then you send them your images and they'll get it all set up for you. I did mine myself and my images are on my own webspace to be pulled for use in my profile.
