Using CSS To Style Your Profile
Every Gold member has access to their profile's stylesheet. DarkPoetry's working on setting up a new customization system but it will take some time.
Meanwhile, here are a sample lines of codes you can use to change your profile:
New Background
Add the following to the end of your stylesheet. The #000 is the hex code for the color, and the url should go to whereever you have your background stored. A new revamped background uploader will be made available soon for you to use.
body{
background: #000 url(http://photobucket.etc/path/to/image.jpg) repeat;
}
More coming soon...
