In addition to helping those seeking a search solution for their enterprise, the ESCenter is meant to be a sandbox where the companies who vend search and related solutions are also invited to play. For starters, we've given search vendors the opportunity to post a working demo of their solution. At beta launch we have a half-dozen demos to show you. Just click on the Demo Center tab in the left-hand navigation bar. If you haven't been to the site before, you may be asked to register. Registration for this site is free. To learn how your enterprise can participate in the Demo Center, see the Services for Advertisers tab on the left-hand navigation bar. (Participation is free.)
