Class.Jabber.PHP is a class which you can use to connect to the Jabber network. It allows you to easily connect to a server and interact with it. It supports all packet types (message, iq, and presence), is very flexible, and offers both high-level methods (registration, message sending, etc.) and low-level methods (packet sending, etc.).
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.
Niiiiiiiiiiiice, but... ...you should REALLY consider adding your name to the class' source code, Jim. ;)
