I'm looking to integrate some sort of collaborative document sharing/editing into my site- something like Google Docs or a writeboard . It doesn't need to be as sophisticated as Google Docs. Probably just the ability to revise plain text documents (and track changes) would be enough. I did wonder about using a wiki, but even this has a lot more features than I need.
Is anyone aware of a freely available (or cheapish) script (pref PHP) to do something similar?
