If you read the CONTRIBUTING file in the CVS checkout, you have to submit them through me. The CVS pserver is specifically designed to prevent access beyond read, to prevent security flaws in CVS from granting access to the rest of the OS. You can submit them to me at krevnikATcomcastDOTnet. (NOTE: Bypassing search crawlers that spammers use, so you have to enter it manually, sorry)
Also my question at last:
How can I put my source on CVS? I didn't do such thing before. My CVS client can download Demolisher sources but I have no idea how to add my sources there correctly. I am planning to add some reversed code from few cdvdman modules there.
