For those who don´t know CM4F, it stands for Community Messaging for Forums. It is a tool that has been developed to integratge mailinglists/yahoogroups, and generally speaking all community tools that can use email communications with forums.
The tool has been iniatally defined for the phpBB forum system, but has been expanded to SMF, NewBB, and other systems.
Due to a huge lack of time, the development has been lagging for somewhile, but now is being retaken.
CM4F for the NewBB forum system will be moving to the www.open-networks.org site, where it has been already integrating some messages in the past.
