I've added a link to the login page that allows you to have your password emailed to you, in case you forget it. This is a feature I've meant to add for awhile, mostly to save me the trouble of having to look up people's passwords for them myself.
You will not be able to use the password reminder unless we have an email address associated with your detective. You can change your account's email address by going to your detective page and click on the "Email" link next to "Account Settings".
Be sure to set that email for each detective you have, otherwise you won't be able to send yourself a password reminder.
