There are 2 ways to approach this. First, you could go into your profile and under the menu heading "Account Related Settings" you can change your "Display Name" to what you like. Your Username will remain the same for the purposes of logging in. The second way is to have your Username changed permanently by an admin. Let us know what you would like your new name to be and we shall change it for you. With this method your Login details will change. If an admin changes your name, your account will be deactivated and a new password will be emailed to you. You will need to reactivate your account from the email
HTH.
