Ringlink is a CGI Perl program that provides the tools you need to run one or more rings of Web sites (i.e., systems of links between Web sites of similar contents).
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
A feature for redirecting a webring that has moved to some other Ringlink system has been added. Automatic notifications are now sent to the ringmaster when the third site gets activated. Various other minor tweaks were made.
