I am a graphic designer who knows the basics of web development? One
of my clients wants to be able to  maintain (add and delete copy) his
own web site without having any experience in web development. I know
that I have to set up an admin page where he can log in, change
whatever he wants to change and then post it. But I don't know how to
code it. I having been searching the web now for a couple of hours
trying to find any information but not having any luck.
