The CentOS Artwork Repository is a collaborative tool that anyone can have access to. However, changing that tool in any form is something that should be requested in the CentOS Developers mailing list. Generally, people download working copies from CentOS Artwork Repository, study the repository organization, make some changes in their working copies, make some tests to verify such changes do work the way expected and finally request access to commit them up to the CentOS Artwork Repository (i.e., the source repository) for others to benefit from them. Once you've received access to commit your changes, there is no need for you to request permission again to commit other changes from your working copy to CentOS Artwork Repository as long as you behave as a good cooperating citizen. Otherwise, your rights to commit changes might be temporarly revoked or completly banished. As a good cooperating citizen one understand of a person who respects the work already done by others and share ideas with authors before changing relevant parts of their work, specially in situations when the access required to realize the changes has been granted already. Of course, there is a time when conversation has taken place, the paths has been traced and changing the work is so obvious that there is no need for you to talk about it; that's because you already did, you already built the trust to keep going. Anyway, the mailing list mentioned above is available for sharing ideas in a way that good relationship between community citizens could be constantly balanced. The relationship between community citizens is monitored by repository administrators. Repository administrators are responsible of granting everything goes the way it needs to go in order for the CentOS Artwork Repository to accomplish its mission which is: to provide a colaborative tool for The CentOS Community where The CentOS Project Corporate Identity is built and maintained by The CentOS Community itself. It is also important to remember that all source files inside CentOS Artwork Repository should comply the terms of in order for them to remain inside the repository.
