Hi, I want to contribute to CentOS, i'm a developer for a long time, and i use RedHat / CentOS. I have experience making builds of packages, now for building to CenOS i use mock, so how i can contribute testing CentOS, solving Bugs. I can't see the CentOS 6 -Beta for testing, and for the others versions 5.5 for example, where are located to sources of the modified packages from RHEL. So if i cat help to test, port or something else, notify to me. Regards.
