I wanna start making my own cms and I'm a little newbie so it will most likely take a long time until I finish, but is there some tutorials around that might help a little ?
I don't think there are tutorials written that will teach you how to make a content mangement system, but my best advice would be to start working on the little scripts and build parts of it and eventually tie them all together as you learn more and more...
