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. RingLeaders has advanced management interface to manage and modify their webrings. 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 accounts/WebRings using a special form.
