The Revision Moderation module allows you to leave existing revisions of a node published while new revisions go into moderation for an administrator to approve.
This module embeds the PJIRC Java IRC client into Drupal and allows visitors to use IRC from any Drupal site. Great for community chat, live support, or a general use IRC client.
This module is no longer supported. Co-maintainer requests will not be accepted.
The Restricted Text module allows users to restrict access to parts of a node body, based on various restrictions. This is implemented as an input filter, so it will only work where other input filters work.
The standalone asterisk module has run its course as a proof-of-concept, and is now no longer needed. The project namespace has been handed over to http://drupal.org/project/voipdrupal for further potential use. Users interested in integrating VoIP with Drupal should now use that project.
