Oh, you're going to enjoy this site, once you get the hang of it. Like Jerry said, check out the FAQ button. In order to put a little picture under your name, find yourself a little image you want to use, no bigger than 50 x 50 pixels. Go to your profile and Edit Options. Look for the options relating to avitars, and I think you'll be able to follow through ok. You can edit any other information you want in your profile, too. That's how you set up a sig file, your location, etc.
Oh bouy, oh bouy, Don's here! He's not lost at sea.
