Nick, have a look at
the CVS Guidelines, particularly the bottom half of the page, re questions 1&4. Once you have an account at openacs.org (and I presume Don, Jeff Davis, Malte, or anyone else on OCT can set you up), you simply commit in your personal -- not anonymous -- checkout. That certainly is all you do to commit within an existing package, and I presume that is what you do to create a new package. But I've only committed stuff to existing packages myself, so I may be wrong on this last point.
