Show informative screen after requesting password reset

When you request to reset your password and submit the form you are informed that the request was successful. However, you remain on the same form and it appears as if you could resubmit the form.

Instead it would be nice to be redirected to a screen saying that you should check your email and reset the password then.

Start by locating the password-reset form and the success handling reached after submission. Trace the current flow, then verify that a successful request reaches an informative screen telling the user to check their email and reset the password rather than leaving the form available for resubmission.
