Re: What's the story behind your user name?
First, make an avatar: Take any picture, crop and size it to 100 x 100 pixels maximum. Save it as a jpeg or png file onto your desktop.
Now go the the User CP (control panel). The link is near the top left of this page, under the thread name. Then click Edit Profile Picture. Now you can use the Choose File button to locate the pic on your desktop to upload. That's it!
