Due to the popularity of this server it is likely it takes a bit to time before you get a reply or even get messages after you send a subscribe command. Mailing lists are in a state of flux but you can find links to a number of interesting lists from the Linux Documentation Homepage . These are intended as the primary starting points to get the background information as well as show you how to solve a specific problem. If you are about to ask any questions about the kernel you should read this first, it will save you and many others a lot of time and possibly embarrassment. Use cat rather than more to view the files as they are reported as being zero length.
Reports are that less works well here.
There are a huge number of informative web sites available. By their very nature they change quickly so do not be surprised if these links become quickly outdated. A good starting point is of course the Linux Documentation Project home page, an information central for documentation, project pages and much more. Please let me know if you have any other leads that can be of interest.
