Wnt to put up a Web site, but your Internet service provider doesn't provide free server space? Head to Geocities (http://www.geocities.com ) or Tripod (http://www.tripod.com ). Both services are advertising-supported and give members up to 2MB of server space--plenty for creating basic sites. Membership is free, but there is one caveat: Both services put restrictions on the content of sites (read the "TOS," or terms of service, posted on the services' home pages for the latest rules). Businesses will find this space most suited for erecting electronic billboards and providing customers with product and service information. But the price--it's free--makes them both very appealing for entrepreneurs who are looking to get a foothold on the Web.
