Userboxes are small template boxes that are made specifically for user pages. They are used for fun purposes for the users, and are never to be used any where else but the user page. Doing so, like any other violation, will be instituted by one or two warnings, and then a two-week block. As well, remember that userboxes are to be used for the users' opinions. Please don't message a user if you disagree with it. Doing so is against policy.
