If you want the ability to wear a signature, purchase a copper membership.
Don't encourage newbie to buy copper membership in order to wear signature. They will spam over forum and this topic is a example. If someone need to post image then he should buy it. To be honest most of new copper member spamming on the forum in my observation.
@OP, you need at least 1 merit become Jr. Member and I don't think you deserve it.
