After you log in, your account data will be displayed with the option to change what you had previously entered. Hit the "Change" button and enter the new information in the form that is displayed. Then click on "Submit" to save your changes.
If you would like to reset your password go to 'Login/Register' and click on the link 'Forgot your password?' or click here. You will be asked for your email address so a password reset link can be sent to you.
If you are unable to access your account since your password is not accepted, ensure you have used the correct email address as your username. Also, ensure that the Caps lock button is not turned on.
If you are still having trouble, request a password reminder or try resetting it. Passwords must be at least 8 characters long and must contain both letters and numbers.
