To change your basic contact information, you can access the Settings page by clicking on the ‘My Settings’ link in the top navigation bar.
This will load the user settings page.
To change your contact information, update either your Name or E-mail and click Save in the black popup bar at the page bottom.
Changing your e-mail will require an extra step to confirm the change. A confirmation e-mail will be sent to both your old and new e-mail, with a link to confirm the changes.
To change your password, type your new password into the password box. You’ll be asked to confirm the change by re-typing your password.
