Your email preferences seem to be broken. I opted out of all emails, and yet I got an email when someone commented on a need I posted. Please, please don't do this. I really hate it when apps do this. I want to like you, so I didn't nuke my account this time. Have a rule in your system which just never sends email to people who don't want to hear from you. </minirant>
