You might want to use a new email address.
When changed, the new email address needs your verification before it gets valid: a verification message will be sent to your new address and you need respond as it requests to get the new address verified.
If you work as a translator, keep in mind you should use the email address that is associated with your PayPal or Moneybookers account. Otherwise we will be unable to make the payment to you via PayPal or Moneybookers.
To change your email address, go to your Account and edit it (how to).
