GLUE is a soapbox engine. It is a PHP/mySQL framework which can be used to set up discussion sites or Weblog sites. Its roots are from Weblogs, but unlike single-person Weblogs, its main focus is discussions. It can be used as simple Weblog software, a discussion site framework, or even as knowledge repository. It features themes, plugins/GLUElets, multiple-categories posts, comments, administration, and user customization, etc.
