How to use the free userbars section:
Find the free userbars you want and simply right click on any of them and choose "Copy". Then right click on your computer and choose "Paste". This will download the userbar, so you will always have it. If you want to use it on the web, just upload it to a free image hosting site, such as www.photobucket.com or imageshack.us. You'll generally want to copy the IMG tag into your post or forum signature. Enjoy!
