If you plan on contributing code to the project, then you will need an account on the CVS server. cvsmaster@gnome.org determines who gets accounts on the CVS server; if you would like one, then send a message detailing what code you have written, what code you plan on writing, along with with a crypted password. You can get that by doing the following:
perl -e 'print crypt ("YourPassword", "salt");'
Where the "salt" string preferably should be a random 2-char string.
