The only way you can change your password is to ask Wade, send him a PM with your requested username (check if it´s free first, if it looks abandoned then you can still ask) and hope for the best. It´s up to him if he thinks it´s worth the effort or not, but you can ask yourself first - does the material connected to this account matter to me? If not then you can save Wade some effort by simply creating a fresh account. If it matters a LOT then make sure to include that in your request as a reason why you don´t want to abandon this one.
