That's how I did it in GradSchool. I took over the web page another student started for the grad-level algorithms class I was taking. The student who started it discovered he had volunteered for too many things. I jumped on it when they needed to change because I needed the extra credit.

Armed with a CD copy of the web site, I moved it over to my hosted space. I setup password-access, and setup the syuidy group, and from there on, I frequently put in one-liner paragraphs from the professor, she sometimes managed to get them to me soon enough that I could put them in before class started that day.
