If you are logged in, there should be a link to your profile on the left side of the screen. There you can edit your name or email by clicking the edit link next to it, and you can change your password by entering a new password in the change password field. Note that by changing your email address, your account will be set back to 'unactivated' and you will be emailed a new activation email to the new email address. You will still have activated privileges until you log out so you can change your email again in case you made a mistake.Also, you can add or edit your bio by clicking the edit button in the about section. This allows you to add information about yourself that anyone can see. Your email address is hidden to other users, but if you wish to share that information you can add it to the bio. Note that a bio is completely optional, and can be edited or deleted as long as you are logged in.
