3. Registering on the Site.

We give visitors to certain Sites the opportunity to register or provide their contact information such as their e-mail address so they can receive updates such as news reports, project or organization reports, opportunities for personal and financial involvement and promotional information. You may also be required to register on the Site to engage in other activities, such as purchases or downloads of materials, services, products, donations, receiving promotions, registering for conferences or activities, or registering for chat rooms or public forums. Personally identifiable information that you provide in these registrations is used consistently with this policy and we will notify you at a particular site if any uses are different than these uses. You can choose not to receive such mailings, or cancel any registrations, by un-subscribing. (See "Opt-In/Opt-Out Communications" below).
