Since I'm no good at graphics, someone made my signatures for me. You have to earn the title of Aes Sedai, here at Tar Valon. I'd recommend reading the Membership Manual and the Bylaws for the site - they detail the process of advancing through the ranks, as well as our rules for User Names, avatars and signatures.
I removed the images you had in your signature for two reasons. One, they were ginormous and violated our site rules. Two, you hotlinked to images that were not yours. If you want to have a signature, we'll definitely work with you to help you find something appropriate.
