[@Multifarious] Well I know it's not something you have to win. It's some kind of coding thing. But I can't quite help you on the specifics. Sadly. :c I will look it up though because I am curious myself. I'll get back to you, if I'm not beaten to the punch. :3

Edit: http://sig.grumpybumpers.com/ Here's a site that will do it. Just create as username/pass. And it will give you the ability to post multiple links. And as long as the preview shows them. All you do, is post that link plus. "[img]" in your "signature" and you should be able to have multiple sig's now. Welcome. xP
