Si te cambias de nombre no perderás tu rango. Así que no te preocupes. Si pierde su rango por algún error. Puede contactar a Joe Henry o enviar un correo a sales@cubecraft.net
I saw Si in the post above, you don't have to contact anyone, you can just change your username, no worries, I also did it. :)
@Scottness , I told him that he will not lose his rank. Also If he has some issues with his rank. He can email sales@cubecraft.net. Please you must be sure before you comment.
