@AlieInBeanland I have changed your username, but unfortunately I can't change your picture. You can try updating it in a different web browser or clear your browser's cookies before trying again. But if that doesn't work you may have to try again at a later time.
@javier.fernando.umss What username would you like to have? I can change it for you. Unfortunately I can't do the same for your profile picture, but you can read what I've written above in this message for a potential solution.
