RingWorld is a CGI script for organizing a WebRing to link together sites featuring the same subject. With RingWorld you can also host your users' WebRings, turning your site into a WebRing server and building your own WebRing community. RingWorld does not require users to support Server Side Includes. This means that RingWorld offers functionality for both SSI and NON-SSI sites. Users can register their site in any WebRing hosted on your server, or register their own WebRing. Users can also modify personal information or cancel their WebRings using a special form.
