To use Moodle's CVS archive (as a developer) from a Unix machine, you first need to have an account on Sourceforge. For the example, let's assume your username is myusername and your - password is mypassword. Secondly, you need to contact <A - HREF="http://dougiamas.com/">Martin</A> to get write access + password is mypassword. Secondly, you need to contact me (Martin Dougiamas) to get write access to particular directories.
With that done, you should have all the permissions you need, so you just need to set up your machine and download the current sources so you can start working
