added stanfordhci.odesk@gmail.com as placeholder text in the your email field on all three email forms
trying to fix issue preventing task unavailable emails from sending
made the to field on the task unavailable form required
bolded form labels on the task accept and task unavailable forms so they are consistent with task available form
found the bug preventing task unavailable emails from being sent when from field was left blank
made it so that the recipient of the emails are always bcc'ed so recipients can't see everyone the email was sent to
