You may choose to browse NSPN without frames. Some websites will link to NSPN with our pages entirely enclosed within one of their own frames. This is very bad net manners, but there is little the NSPN website can do about it. This means that the page you are viewing may not contain the most current information. If the date doesn't change, you have the most recent page.
Some frame based sites display the pages of other sites within their own frames.
This is a misleading practice since it make the content of another site appear as if it is your own. If the practice is not illegal, it is at least bad manners, and the NSPN attempts to avoid it. Some people have expressed difficulty printing frames. All frames are created equal, and your browser cannot know which frame you want to print unless you give it some indication. Simply click your mouse somewhere in the frame you want to print before you select the print command.
