Once logged in you can change your password from your Profile page. Unless the administrator has configured the site to allow username changes you cannot change you username. Otherwise you can change your username from the Profile page. Once logged in, you can change your private email address from your Profile page. The only profile setting that is required is your private email address. This is the email address that is used when you subscribe to the forums, when a forgotten username/password is emailed. The private email address is never shared or displayed publicly. If you wish to share an email address publicly, use the public email address field. The remainder of the profile settings is optional. You can set the option in your profile and your name will not appear in any member listings, including the listing of who is online.
