Opengroupware.org
Nice to know about the
OpenGroupware.org project, an open source groupware server, developed
by a company which have now opened the software. Very nice news, since a groupware
server is one of the missing things in the Free Software world.
There are several clients which already work with this server, including Mozilla,
Evolution (via Ximian Connector), and others (see their web page for full details).
