You can not change your own Classifieds username, but we can change it for you.
Please fill in the Support Center "contact us" form to send us an email, selecting "Classifeds" in the Queue field. To expedite the request, put "Change Classifieds Username" in the subject field.
In the body section of the form, provide your current username, the email address you registered with, and your city, along with the new username you would like. The new username must be 6 - 12 characters long. Please allow 24-48 hours for the change to be made.
