When I'm asked to do revisions on a Website, I usually have the non-technical editor print out pages in question with comments/revisions written in ink, but this obviously has it's drawbacks.
I was wondering if anyone was familiar with a Firefox/Chrome add-on/extension (thinking like a GreaseMonkey type script maybe) or an application that would allow a non-technical person to add comments/revisions to "live" pages, even if it was just typing over it or similar to how Word does it with the built-in collaboration feature.
