Can I suggest 2 Linux forums which provide distro forums with subforums which some might find helpful.
You might already use them, I use both particularly Ubuntu as it is my main distro
Red Hat / Fedora Linux
Ubuntu Linux, which I follow and find very useful
Other Linux Distributions
http://www.linuxquestions.org/ I find this the best as it has more detail
Linux -Netbook and laptop
Linux From Scratch
LFS is a project that provides you with the steps necessary to build your own custom Linux system.
