Personal Information You Choose to Provide

We will not sell, trade, or in any other manner intentionally distribute, disseminate, or
disclose any personal identification information about you (such as, for example, your
full name, street or mailing address, telephone number or e-mail address) as an individual user of this web site to any companies, organizations, individuals, or any other third party

obtaining your permission.
 We may request personal identification information from you in connection with your use
of, or participation in, surveys, e-mail correspondence, bulletin boards, chat rooms, wikis and other collaborative spaces, mailing list registrations enabling you to receive our publications, or teacher registrations enabling teachers to participate in curriculum field-tests, workshops, and/or other TERC project activities.

 may also keep your comments or questions for future reference.
It is important to note that if you give out personal information online, through a wiki space, bulletin 
board or chat room, for example, that information may be collected and used by third
 parties. We cannot guarantee the security of information you post in these arenas. You
