The first step is for all developers to start using cvs.moodle.org as the address of the CVS server. Currently this is an alias pointing to Sourceforge so it's effectively the same as always. The difference is that I can change this alias in future to a new server anytime and you should experience minimal disruption.
Switching CVS servers is very easy on Linux, just run this in the main Moodle directory to edit all your Root files:
find . -type f -name Root -print0 | xargs -0 perl -pi -e 's/\@moodle\.cvs\.sourceforge\.net/\@cvs\.moodle\.org/'
For more information about the rest of the plan as it develops, track MDLSITE-192.
(Please don't follow-up with suggestions about SVN, Git etc, we're sticking with CVS for a while at least
