Looking For Projects That Need Documentation?

ijones asks: "I have several friends who are professional writers. They're capable of understanding technical & computer things well enough to write about them, and I want to get them into technical documentation (with the ultimate goal of getting them hired at some computer company some day). It would be nice for them to get experience and help out open source projects by writing documentation for some open source software, but software like CVS or GDB is no good since they'd have some trouble understanding what the software is for. Are there any projects out there which could use some documentation that non-geeks could understand well enough to write the documentation? Is there a good clearinghouse for still-to-be-written documentation?"
