The registry used to be a custom-developed web application but this has proven to be too maintenance intensive and nothing much happened to the site for several years, as many have noted. Therefore, this new version of the Registry has been created based on the Drupal CMS. Drupal allowed us to provide the complete registry with a minimum of coding effort, through its excellent Content Construction Kit and Views modules. My hope is that it will prove much easier to maintain and also allow others to take a more active role, not just me and authors but also artists and other contributors!
This site is still in beta and if you have any suggestions, criticism or the like, please post it to the Site discussion forum!
