Link Conservatory is a link indexing / directory management system written in PHP3 that uses a MySQL database on backend. With Link Conservatory software, users of your site can add, modify, or remove links in a moderated or unmoderated fashion, and outside visitors can suggest links for inclusion in a moderated Conservatory. Users can also be notified by e-mail as new links are added. Other key features include: dynamic tree expansion at any given category, link search engine, top 10 most popular links, a list of the last ten items added, random link generation, and more. Since it is
open-source, you are free to customize the program to make it unique to your organization.
