We use two types: persistent cookies and
session cookies. A persistent cookie helps us recognize you as a user.
After you sign in, a persistent cookie stays in your browser and will be
read by our site when you return to the site. Session cookies only last
for as long as the session (usually the current visit to a site or a
browser session).

We also have implemented and use Google
Analytics Display Advertising, specifically the Demographics and
Interest Reporting feature to advertise online, sell advertising, and
develop content.

We also may use Adobe Flash, which is
another technology that can provide cookie-equivalent functionality.
Adobe Flash is capable of storing information on your device (in a file
outside of your browser).
