How can I change my password? I was sent a recovery password and told to change it within 4 hours however it will not let me change my password.

You can change your password on the Main account page

Unfortunately, it appears the password changing tool is currently broken, at least based on my experience with it. I've tried four times to reset my password in the last 24 hours. Each time I Get a temporary password e-mailed to me and can log in using that, but if I change my password, log out, and attempt to log in with my new password it still fails.
