Hey everyone, I am a website designer, and am looking for a content management system so that my customers can log into the backend and change the main text on there site, and that is all, I dont want them to do anything else, just change text.

But I also want the program to be versatile to my layouts, so i can have any HTML file (my template) and then add some DIV codes, or so on, and in these DIV codes, the CMS will add, modify and delete the text in here only.

Any ideas of some programs or coding i can use???
