Well this headline will set off the email filters. That's why you should whitelist domains you know are safe. Anyhow, this item describes a new software release from the African Virtual Open Initiative and Resources project (AVOIR), "a sophisticated group-based collaboration system, supporting an unlimited number of groups... where you have complete control over what functionality is installed, as well as what functionality is available on a per group basis. You can use kGroups to replace wikis, blogs, content management, mailing lists, document management, instant messaging, discussion forums, and dozens of other applications." Based on PHP (version 4.x but not 5) and the Pear framework. Good stuff.
