Sponsors may require the email ids of participants. Since this is a reasonable request and the sponsors are responsible people who most probably will be making job offers, we have decided to give them the list on request if they undertake not to spam or share the information.

We have added a private box to your profile which you may tick to indicate that you do not want your email address disclosed to the sponsors.

You can use the http://in.pycon.org/2009/edituser/ URL to access your profile and change this setting.
