New feature - you can edit a lot of stuff on the profile pages now. Use the link:
Customize Profile link to edit colors and backgrounds for your user profile. You can also add friends from the forum and create/access user forum photo albums (when I get it to work right), leave messages, etc. Kind of like a mini MySpace.
To see a member profile, click on the member's name from any post amd select "View Public Profile" or to view your own, go into the "My Settings" area and then click on the "Your Profile" link.
