[QUOTE=John_W;682989]The saying at the bottom of your post is 'your signature'. You can put an image like mine, or write a slogan, or whatever you want. Go to 'UserCP' at the top left of the page, then click on edit signature. If you want an image next your screen name, that is called your 'avatar'. It's in the same control section, but you'll need to reduce the size of most images.
As far as changing your screen name, you'll probably need to contact the moderator or administrator, unless you have another email address.
Thank you! Now I just have to think of a clever signature.
