NS uses Google Adsense to deliver ads tailored to each user, and Google recently updated their Advertising Cookie and Privacy Policies. And as a result of that, I've updated the forum rules/terms of agreement that you agreed to when you first registered here on NS, and is now implemented for all users, new or old.

The changes made is reflected below:

We use third-party advertising companies to serve ads when you visit our website.

Some information about the DART cookie from Google Adsense website:

The DoubleClick DART cookie is used by Google in the ads served on the websites of its partners, such as websites displaying AdSense ads or participating in Google certified ad networks. When users visit a partner's website and either view or click on an ad, a cookie may be dropped on that end user's browser. The data gathered from these cookies will be used to help better serve and manage ads on the publisher's site(s) and across the web.
