Hi, Why does http://www.centos.org/docs not point to say this for example: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/index.html The latter is more comprehensive. The links that http://www.centos.org/docs contains all have "upstream" labels on the reading material, so I'm guessing the trademark boundries are not being crossed. Regards, Paul (Crunch)
