Now that I'm re-registered how did I update my profile?
User CP (Control Panel) link is at the top of the page below the FerrariChat Logo. That will take you to a wonderful place where options abound. But, everything on the board looks new (you'll get used to it, it's much more efficient) to you, so click this link for the shortest route to your profile. Once you're done (for a while) with your profile, spend some time looking at the whole Control Panel section. You'll get a better grasp of what the possibilities are; Pics, avatars, how you want to see posts and backgrounds, all kinds of stuff.
