Friendly URLs (or Marketing URLs) exist as a way to format the oft-intimidating URLs created by the CMS, such as http://www.farcrycms.org/index.cfm?objectid=A762FA21-EA69-0EC7-F9213952134B86E8, and turn them into something more palatable like http://www.farcrycms.org/go/downloads/release-notes.

The Administrator can view and delete these Friendly URLs through Manage Friendly URLs; as well as rebuild the list of all the pages on the site using the Rebuild Friendly URLs button. 

Warning Be careful running the Rebuild Friendly URLs function on a live site as it will severely hamper performance.

For more information on the subject, go to the Friendly URL Management page in the Developer's Guide.
